Risks for dogs include obstruction and alcohol poisoning
My husband has recently taken up the delicious hobby of artisan bread baking. Although this is a pursuit my belly fully supports, it has reminded me of the dangers that raw bread dough poses for our pets. The risks are twofold. The first problem is that dough rapidly rises after ingestion and can cause life-threatening stomach distention and obstruction. The second—and potentially more serious—risk comes from the fermentation of the yeast, which can lead to alcohol poisoning.
Any species can be susceptible, but dogs are most commonly involved due to their often indiscriminate eating habits. Given the opportunity, many dogs will readily ingest bread dough during the process of rising, and because they snarf all that is available, they usually consume 1 to 2 loaves or a pan of rolls. They don’t think, “Hmm, I’ll just save this one loaf for later,” so they generally present with large amounts in their stomachs.
A common scenario is that the soon-to-be bread is placed on a counter to rise overnight, and the next morning the owner wakes to find missing dough and a symptomatic dog. I treated a Labrador for alcohol poisoning just this past weekend after he ate two pizza dough rounds. He stumbled into the hospital with his worried parents but went on to make a full recovery with treatment.
How does it happen?
The warm, moist environment of the stomach serves as an efficient incubator for the replication of yeast within the dough. The expanding dough mass causes distention of the stomach, which compromises blood circulation in the body. The continued distention of the stomach can also make breathing more difficult.
Yeast fermentation also produces ethanol (alcohol) as a byproduct, which is absorbed into the bloodstream, resulting in inebriation and potentially life-threatening disturbances to a pet’s system.
What are the clinical signs?
Early signs can include unproductive attempts at vomiting, visible belly distention and increasing depression. As ethanol intoxication develops, the pet can stagger and become disoriented. Eventually, profound neurological depression, weakness, coma, low body temperature and/or seizures can be seen. Death is usually due to the effects of alcohol rather than from the stomach distention, however, the potential for the dough to trigger life-threatening Gastric Dilatation and Volvulus (GDV or “bloat”) or intestinal obstruction should not be overlooked. [See: Bloat, the Mother of All Emergencies]
How is it diagnosed?
Blood alcohol levels can be obtained through a laboratory, but are generally not used in a veterinary setting; a presumptive diagnosis is usually made based on history of exposure and presenting clinical signs. Other disease processes that can present in a similar way include GDV, other intestinal foreign bodies, ethylene glycol ingestion (antifreeze) and ingestion of antidepressants.
How is it treated?
Vomiting may be induced with recent ingestion in animals not showing clinical signs, although the glutinous nature of bread dough may make removal by this method difficult. In animals where vomiting has been unsuccessful, gastric lavage may be attempted (“flushing” the dog’s stomach with water while he is under anesthesia).
Cold water introduced into the stomach through a stomach tube during lavage may slow the rate of yeast fermentation and aid in removal of the dough. Surgical removal of the dough mass may also be required if a large enough amount has been ingested.
Pets that present with the additional signs of alcohol toxicity first need to be stabilized and have any life-threatening conditions corrected before attempts are made to remove the dough. Alcohol toxicity is managed by correcting metabolic problems, managing heart abnormalities and helping the pet maintain his normal body temperature. Fluid therapy is administered to help enhance elimination of the alcohol from the blood stream.
Luckily, the dog I treated this past weekend did not require surgery. We supported him with IV fluids and took serial X-rays to monitor the passage of the dough, ensuring no complications developed. Aside from a pizza dough hangover, he made a full recovery in 36 hours.
As always, prevention is the best treatment: If you have a fabulous baker boy (or girl) in your home, be extra conscientious during the rise!

Tips for keeping your pet merry this season
O Christmas Tree! O Christmas Tree! You are beautiful, but you can hurt me!
As the holiday season gears up, have you noticed that with the increase in fun and festivities comes a simultaneous increase in the level pet mischief? There just seems to be no way for our curious pups to resist the allure of all that holiday paraphernalia.
Below is a list (all naughty, no nice!) of the common problems I treat on an emergency basis:
Decorative lights on the tree can pose a serious electrocution hazard when chewed. Signs of electric shock range from a dazed and confused behavior to difficulty breathing, burn injuries in the mouth, seizures and potentially sudden death. Immediate evaluation by a veterinarian is recommended if you suspect electrocution. Take appropriate precautions to ensure lights are hung out of reach and the cord is adequately protected. Use grounded three-prong extension cords and strictly follow manufacturer's guidelines for light usage.
Tinsel and ribbon can potentially cause an obstruction in the intestines when ingested. In medical terms, we refer to these items as “linear foreign bodies,” and they have significant potential to get bound up within the intestinal tract causing a blockage, and in some cases, cutting through the intestines.
Most often, these linear foreign bodies get “hung up” in the intestines, causing deadly “bunching” and can only be removed by surgical means. If you notice a bit of ribbon, tinsel or string, whether from the mouth or the other end (see photo), it is important to remember never cut the ribbon or attempt to remove it yourself! Seek veterinary care immediately.
Vomiting, diarrhea, loss of appetite and depression will be the most common abnormalities seen when an intestinal obstruction is developing, and early surgical care is essential. Exercise extreme caution and never leave pets unattended around string, tinsel and ribbon.
Ornaments may be ingested and have potential to cause an obstruction leading to the need for surgery. Ornaments made of glass can fall and break, leading to cuts and other injuries. Adequately secure ornaments and place them above the reach of wandering paws and curious noses.
Tree-stand water contains preservatives and sap that may cause vomiting and diarrhea.
Festive plants are often displayed during the holidays and precautions should be taken to avoid ingestion of any plant. Even “nontoxic” plant material, such as pine needles, may cause stomach upset.
Common holiday plants to take particular note of include:
Potpourri is often used around the house to put us in the holiday mood. The plant material and some additives are very irritating to the skin, mouth and intestinal tract. If skin exposure is suspected, then bathing with a mild soap is recommended and medical care may be needed to treat irritation and pain that follow exposure. Ingestion often results in signs that may include drooling, loss of appetite, vomiting, and in some cases, disorientation.
Treats are a common source of holiday emergencies. While it can be hard to resist your pleading pet’s eyes, it is important to recognize the dangers of particular foods and treats:
“People foods” that we take for granted as being safe for us are not always safe for our pets. Raisins and grapes have been implicated in causing kidney failure in dogs. Onion ingestion can cause blood cell damage in both dogs and cats. Chocolate contains caffeine and a caffeine-like substance (theobromine) that dogs and cats are highly sensitive to causing stomach upset, tremors, seizures and irregular heartbeat. Macadamia nuts cause dogs to show a variety of strange neurological signs that can include weakness, apparent pain, disorientation and tremors.
I hope this information helps you and your four-legged family members avoid any “bah-humbugs” this holiday season!

New York Times Bulldog story exposes serious health issues, deep denial
In 2008, the BBC documentary “Pedigree Dogs Exposed”—which revealed high levels of disability, deformity and disease among purebred dogs—dropped like a bomb on the world of dog shows and breeding in the United Kingdom. A year-and-a-half later, the UK’s Kennel Club initiated steps to reform its practices and standards.
Three years later, questions and calls for reform are finally gaining traction here. In April, the Humane Society of the United States convened “The Purebred Paradox” conference to explore issues like those being debated across the pond, and featuring some of those key players. In September, John Woestendiek presented the state of the debate in a feature for Bark (“Breeding Paradox: Can dog-breeding practices be changed?”)
And last Sunday, Benoit Denizet-Lewis added The New York Times’s high profile voice to the conversation with a Magazine cover story on the poor benighted Bulldog (“Can the Bulldog Be Saved?”). The mascot for the Marines and many college sports programs just might become the most enduring example of breeding gone wrong.
Is this a topic near and dear to your heart? Read up on the recent coverage and check back, we’ll be hosting an online conversation with experts soon.

What you need to know about this life-threatening condition for dogs
There is no quicker way to jump to the front of the ER line than if you walk into the hospital with a distended dog. Bloat is a life-threatening condition that I treat frequently, and a good outcome is time-dependent.
Last week, JoAnna Lou wrote about recognizing the signs of bloat and included an educational video of an Akita experiencing GDV (don’t worry, he survived!). This topic elicited excellent comments and questions, prompting me to want to expand upon it further. I hope to answer some of the questions put forth by readers as well as dispel misconceptions that could potentially harm your pet.
First, some vocabulary: Bloat is a condition when the stomach fills with air and/or fluid (dilatation). This can progress to a twisting of the stomach upon itself, called GDV (gastric dilatation volvulus). Bloat is often used to describe GDV, but there is a vast medical difference. We’ll get to the details of GDV in a moment, but let’s start with the most important take-home message:
If you even remotely suspect bloat or GDV, take your dog to a veterinary hospital IMMEDIATELY!
What NOT to do:
A note about the use of Gas X: This medication may help to reduce the amount of stomach gas in the case of “simple” bloat, but it will do nothing to help your pet in the case of GDV. The problem with GDV is not the gas, but the actual twisting of the stomach (think of a balloon being twisted in half, like when a clown makes an animal figure). It is the twist that kills, and a medication will not undo the deadly rotation of the stomach. Please do not waste valuable life-saving moments waiting to see if the medication helps! Taking an x-ray of your pet’s abdomen is the only way to tell the difference between bloat and GDV, allowing for appropriate intervention.
What is GDV and why is it so serious?
The twisted and bloated stomach presses on the major blood vessels that carry blood back to the heart, stopping normal circulation and sending the dog into shock. Making matters worse, the stomach tissue is literally dying because it is stretched tightly and blood cannot circulate through it. Intense pain is associated with this disease, causing the heart to race at such a high rate that heart failure will result.
There can be no recovery until the stomach is surgically untwisted and the gas is released. A dog with GDV will die in a matter of hours unless surgery is performed. For each hour that goes by, there is a greater risk for complications during surgery as well as during the recovery period.
What are the signs of GDV or bloat?
View some of these bloat symptoms in the video we posted last week.
What dogs are at risk?
Classically, this condition affects deep-chested breeds, and dogs with deep chests that weigh more than 99 pounds have a 20 percent risk of bloat. Although a rare occurrence, I have also treated three small-breed dogs for this condition in my ten-year career.
There are many theories regarding what triggers GDV, but truly, no one really knows—it remains a veterinary medical mystery. Risk factors, lifestyle and personality profiles that may increase a dog’s potential for developing GDV have been identified over the years and include:
On the flip side, the following factors may decrease the risk of GDV:
One day after treating Bauer for bloat, veterinarian Shea Cox scheduled him for surgery to prevent the more serious GDV.
What else can I do?
For breeds with a high risk of bloat, a preventive surgery called prophylactic gastropexy can be performed at the time of spay or neuter. Gastropexy involves surgically “tacking down” the stomach to the inside of the abdomen to prevent rotation. If your dog has already been spayed or neutered, the same procedure can be done laparoscopically, and is minimally invasive. I had this procedure performed on my own Dobie, Bauer. I saw him bloat (and thankfully not twist!) one day at the park, and treated him at work. The next day, I scheduled the laparoscopic procedure.
This is a same-day surgery with a quick and comfortable recovery. In the Bay Area, the cost is generally $1,500–$2,000, which is far cheaper than emergency surgery, and worth its weight in gold for peace of mind. One of my biggest fears was to have Bauer bloat while I was away for the day, only to return home to find I was too late.
It should be noted that gastropexy does not prevent future bloat, but it does prevent future twisting, which is the deadly component of the condition.
What is the prognosis?
Decades ago, a diagnosis of bloat was almost always a death sentence, and only 25 percent of pets with bloat survived. Today, the survival rate is better than 80 percent! Part of the reason for this is increased owner awareness (go, pet parents!) leading to rapid intervention and treatment. The earlier the veterinarian gets started with treatment, the better chance for survival. Extremely aggressive medical and surgical intervention early in the course of the disease has the most dramatic impact on overall success.
This is a condition I see much too frequently, but I have to say from personal experience, nearly all dogs return home (95 percent or greater) with early and appropriate treatment.
Being the doting mom of two Dobies, this is a subject that hits close to home, and one I have experienced personally. Thank you to JoAnna for helping raise awareness of this all-too-common condition in our large-breed babies. Feel free to ask questions; I am happy to further elaborate on any area. For now, I’m off to hug my boy, being especially thankful that he is with me today.

A veterinarian with a potentially sick dog needed to know
Thanks to everyone who replied to my post, A Death in the Pack. Your stories and advice were both comforting and enlightening. Happily, Renzo dodged any long-term ill effects of his raisin binge and was back on stride within a few days.
But there was one aspect of Raisingate that was not satisfactory. When I first brought Renzo in, my veterinarian tried to assess how many raisins he may have ingested by eating approximately a half a box of Kellogg’s Raisin Bran. She called Kellogg’s to ask and was told it was proprietary information the company couldn’t release.
She was trying to figure out if he’d consumed more than three ounces, which would make a big difference in toxicity and treatment strategy—essentially, one day of fluids versus three days.
Thanks to the Internet and a skeptical engineering student, my vet was able to crack this carefully guarded secret with a few strikes of the keyboard! Aspiring Polymath: Adrian Corscadden decided to challenge Kellogg’s two scoops claim and actually separated out the raisins and weighed them. (His judgment: Barely a cup, or 150 grams in the 475 gram box.)
While Adrian was bothered by the vague “2 scoops” claim, I was peeved by Kellogg’s disregard for my dog. My business-savvy friends tell me it’s the way business is done. Sick dog be damned! Companies need to protect their intellectual property. I get that. I understand why they might not want to reveal a secret recipe. But anyone—including Corscadden, spikebythesea and Chow.com—can eventually separate out and weigh the raisins, so it’s hardly top secret.
So thanks to all of you out there who like to count and measure and record your discoveries. I’m not the only dog mom who’s grateful you did (at least one commenter on Adrian’s blog mentioned needing the information for this same reason). As for Kellogg’s, count me unhappy.

Fatty turkey trimmings can set the stage for pancreatitis
Tomorrow is Thanksgiving, and for many families this means the tradition of spending the day preparing and enjoying a delicious turkey dinner with all of the trimmings. Us humans are not the only ones who look forward to this meal, and I see many dogs in the ER after they have decided to help themselves to a serving or two. While our pets may find this to be an initially satisfying (albeit naughty) indulgence, it can set them up for the development of pancreatitis, a potentially life-threatening disease.
What is the job of the pancreas?
The pancreas is an organ that sits cozily just under the stomach and along the first part of the small intestine. The pancreas is all about secretion and it has two main jobs. The first is the secretion of digestive enzymes to help break down food, and the second is the secretion of insulin and glucagon (to regulate sugar metabolism). The digestive enzymes are the part of the story that concerns us in pancreatitis.
Just what is pancreatitis?
Put simply, pancreatitis is inflammation of the pancreas that disrupts its normal integrity. Digestive enzymes that are normally safely stored are released prematurely, beginning to digest the body itself, and the result can be a metabolic catastrophe. As the tissue becomes further inflamed, the damage begins to involve its next-door neighbor, the liver. Toxins released from this progressive party of tissue destruction can circulate more broadly, causing a body-wide inflammatory response. If the pancreas is severely affected, its ability to produce insulin can be affected and diabetes can result.
The good news is that most commonly the inflammation is confined to the area of the liver and pancreas, and most pets make a full recovery with support.
What causes pancreatitis?
In most cases, we never find out what causes it but we do know some events that trigger it. These can include:
Miniature Schnauzers are predisposed to pancreatitis as they commonly have altered fat metabolisms.
Signs of Pancreatitis
The classical signs are appetite loss, vomiting, diarrhea, painful belly, depressed attitude and fever.
Making the Diagnosis
Until recently, a reliable blood test has been lacking. A new newer generation option called the SPEC cPL (specific canine pancreatic lipase) test has come to be the lab test of choice. For dogs only, the SPEC cPL can be run overnight by a reference lab and is able to detect 83 percent of pancreatitis cases and exclude other possible diseases in 98 percent of cases.
This test should not be confused with the “in-hospital” pancreatic test, which resembles a “pregnancy test” and gives you an answer of “abnormal” or “normal.” I am personally not a huge fan of this test because other disease processes (such as liver or gastrointestinal disease) can cause an “abnormal” result.
Ultrasound detects 68 percent of cases and provides the opportunity to look at other organs. Since pancreatitis can be accompanied by a tumor near the pancreas, ultrasound is an important tool for catching such complicating factors. I discuss and recommend this diagnostic for all patients I suspect have pancreatitis.
The passage of food through the intestine is a strong stimulus to the pancreas, which is what we want to avoid. Essentially, we want the pancreas to “rest.” This generally means no food or water for 2 to 3 days (in our very ill patients) using IV fluid support to prevent dehydration. Fluid support generally requires electrolyte supplementation and a critical patient will need 24-hour care with blood-test monitoring several times a day. A plasma transfusion represents a specific type of fluid therapy and may be of great help in severe cases.
Pancreatitis can be a very painful condition and pain management is of utmost importance in recovery and is a cornerstone of treatment. Untreated pain affects the immune system and has been shown to increase death rate. Medications to control nausea are also used. Antibiotics are used because even though pancreatitis is not a bacterial disease, bacterial invasion from the diseased intestine is a common occurrence.
Once the patient has started to eat again, a low-fat diet is important to minimize pancreatic stimulation. Since there is potential for the pancreas to always have a smoldering bit of inflammation, long-term use of a low-fat diet is likely to be recommended.
Pancreatitis can be a very severe disease to experience and treat and I hope this helps raise awareness of a potential source of calamity. Please remember to keep your countertops pet-safe: Take all garbage outside promptly and be extra vigilant of the fact that even the most well behaved pets can be tempted with all of the food festivities.
Here’s to a SAFE, happy and wonderful Thanksgiving!
Dog's Life: Lifestyle
See what the symptoms look like in real life
Everyone with a large, deep chested dog is always worried about bloat (any breed can get bloat, but this demographic is disproportionally affected). Bloat is particularly scary because of how fast the condition becomes serious.
When bloat occurs, the dog’s stomach fills with air, fluid and/or food. The enlarged stomach puts pressure on other organs and can cause difficulty breathing and even damage to vital organs.
According to the ASPCA, even with immediate treatment, approximately 25 to 40 percent of dogs die from this condition. But certainly the odds are much better the sooner the dog can get emergency treatment.
I'm familiar with the signs of bloat, but the video below helped me learn what the symptoms look like in real life.
Roscoe, the dog in the clip, was adopted from Akita Rescue Mid-Atlantic Coast. The video was taken when he first got to his new home. No one present had ever seen bloat before. As soon as they realized Roscoe was sick, they rushed him to the emergency vet where he received life-saving treatment.
Thanks to this video, I feel much more confident that I could identify the symptoms of bloat.

Causes, risks and treatment of cataracts
When you look into your dog’s eyes, what should you see? If your pet is healthy, bright, shiny and clear eyes should be looking back at you. (Well, OK… those three qualities plus a pleading expression, begging for that last bite of whatever it is you are eating.) However, if your dog’s eyes begin to look a little cloudy or bluish-gray, it could indicate that cataracts are forming, which is a sign for you to take him or her to your veterinarian for further evaluation.
So, just what is a cataract?
Cataracts are characterized by the development of opacity in the lens of the eye. The lens is the normally clear structure that sits directly behind the iris (the colored part of the eye), and its job is to focus light as it moves toward the back part of the eye (the retina). Despite its clarity, the lens is in fact made of tissue fibers. As an animal ages, these fibers become more dense and compact, preventing the passage of light to the retina, leading to blindness.
What causes them to develop?
The most common cause of cataract formation is due to hereditary disease. Other causes include congenital (born with it), senile cataracts (age-related), diabetes, trauma, dietary deficiency (milk replacement formulas that are low in arginine or phenylalanine have been implicated as well as puppies fed strictly evaporated milk formulas or goats milk), electric shock or toxins.
Why is it bad to have a cataract?
A cataract by itself does not necessarily require treatment. If the only problem is blindness, and there is no associated inflammation or glaucoma, it is perfectly reasonable to have a blind pet, as dogs do not depend on vision the way humans do. Blind animals can have an excellent life quality and can adjust well to vision loss (though it is important not to move furniture around or leave any hazardous clutter in the home). Some dogs, however, do become anxious—or even aggressive—when they lose their vision.
Of bigger concern is the fact that a cataract can luxate, meaning it can slip from the tissue strands that hold it in place and end up floating around in the eye, causing damage. Furthermore, if a cataract settles in a place blocking the natural fluid drainage of the eye, a buildup in eye pressure (glaucoma) can result, leading to pain and permanent blindness.
Another problem is the fact that cataracts can begin to liquefy and dissolve after a long time. While this sounds like it should be a good thing, it is a highly inflammatory process, and creates a condition called uveitis. This is a very painful eye disease that can also lead to glaucoma.
How are cataracts treated?
Cataract treatment generally involves surgical removal or physical dissolution (“breaking up”) of the cataract under anesthesia. The ideal time for cataract surgery is the immature or early mature cataract stage.
Obviously, the pet must also be in good general health to undergo treatment. For example, a diabetic dog must be well regulated before cataract surgery. Also, in order for a pet to be a good surgical candidate, he or she must also have a temperament conducive to having eye drops administered at home. Lab work is performed prior to anesthesia and some ophthalmologists also request that pets have their teeth cleaned prior to surgery to minimize sources of infection for the eye.
Historically, removing the cataract meant surgically cutting into the eye and physically removing the lens. (This short video shows a cataract removal—not as daunting as one would think!) This is still done for older patients whose lenses are compact, but for younger patients where the lens is still soft, a technique called phacoemulsification is preferred.
This technique has become the most common method of removing cataracts in dogs. Here, the lens is broken apart by sound waves and sucked out with a gadget similar to a tiny—a few millimeters wide—vacuum cleaner. Artificial lenses are implanted at the time of surgery, restoring essentially normal vision. (Without the artificial lens, the dog’s vision will be approximately 20/800, and objects will appear to be reversed, as in a mirror.)
Cataract surgery is performed routinely with an overall 80 to 90 percent success rate. Long term prognosis following cataract surgery is very good to excellent. Overall, a 95 percent vision rate is reported immediately after cataract surgery, and once cataracts are removed, they cannot return!
What else could it be?
During exams, people often raise the concern that a cataract is developing in their pet’s eye. Generally, the vast majority of the time the pet does not have cataracts, but instead has the much more common condition known as nuclear sclerosis.
Nuclear sclerosis is a normal change that occurs in the lenses of older dogs and it appears as a slight graying of the lens. The older, denser lens begins to appear cloudy. It usually occurs in both eyes at the same time and occurs in most dogs over six years of age. The condition does not significantly affect vision and treatment is not needed.
How your veterinarian can tell the difference between a cataract and nuclear sclerosis is by shining a bright light into the eye. With a cataract, you are unable to see to the back of the eye (the retina); with nuclear sclerosis, you can still see the retina. In the pictures below, you can see how easily nuclear sclerosis (left) might be mistaken for a cataract (right).
If you observe cloudiness in one or both of your dog's eyes, you should bring him or her to see your veterinarian for further evaluation. Your veterinarian can perform a complete physical examination, focusing on the eyes, helping to determine the severity of the problem. Restoring vision for your pet can then be weighed against risk and expense, and it is a personal decision for each family to make.

The 411 on your dog’s anal glands
No butts about it, anal gland issues are not at the top of anyone’s conversation list. However, it is a fairly common problem that occurs in many of our pets.
Anal sac impaction most often results in only minor irritation (or, shall we say, “rear-itation”), but if left unchecked, an anal sac abscess can develop. This is a common complication that I see in the ER. Owners usually present their pet for “bleeding from the rectum,” when in reality, it is a ruptured anal sac that is draining blood-tinged fluid. It’s what I refer to as “anal sacs gone bad.”
What are they?
Anal sacs are two grape-sized glands just inside of your pet’s anus that contain a foul-smelling material. Prior to domestication, these glands served the purpose of marking an animal’s territory, and could be readily emptied voluntarily. Pets nowadays have largely lost their ability to empty their sacs on demand, and the process occurs naturally during normal defecation when firm feces are passed, lubricating the anal opening in the process. Glands can also “spontaneously empty” during times of stress or excitement; you can recognize this has happened if your dog suddenly develops a very unpleasant odor.
What is the anatomy?
The drawing (below, left) shows the location of normal-appearing anal glands in the dog. The glands lie beneath the surface of this skin and are not something that you can visibly see. The second image (below, right) shows both an inflamed anal gland as well as a ruptured anal gland (more on this below).
How does it happen?
Anal sacs become impacted when a blockage develops in the duct that leads from the gland to the anus. Main causes for the development of a blockage in the duct include having a softer stool or diarrhea, allergies that result in inflammation of the sac and duct, or just plain luck of the genetic draw. Surprisingly, worms are NOT a general cause. (It is a common misconception that a “dog scooting” means that your dog has worms.)
At this stage, the gland is generally swollen and not painful. However, if an infection develops the area can then become painful, swollen and sometimes result in the formation of an abscess. Infection develops because blockage of the duct results in inflammation of those local tissues. In general, when any tissue is inflamed it is no longer happy and healthy, making it easy for the bacteria that normally live in the area to get out of check and “take over,” causing an infection.
How can I tell if my pet’s anal sacs are causing a problem?
One of the first things owners often report is a “scooting” behavior; they observe their pets dragging their bottoms along the floor or carpeting in an attempt to empty the glands. Some dogs will also lick the anal area while others will nip and bite at their bottom or chase their tails.
How is it treated?
I bravely tackled the mission of watching a disturbing array of YouTube videos, trying to find one that best demonstrated the task properly. This video provides a good illustration of the task. It may be considered graphic by some, so please don’t click the link if you are easily queasy—some things are best left to professionals.
Can I express my pet’s anal glands at home?
Obviously, this is not for everyone, but if you feel comfortable doing so, this is a procedure that can be done at home. It is strongly recommended that you have your veterinarian or groomer demonstrate how to do this for you, for your first time. A second pair of hands up at the front of your dog or cat is helpful to give distracting rubs on the head and praise. A word of caution: Expressing incorrectly can cause irritation and lead to further problems so make sure you are able to perform the task correctly.
What if the scooting continues?
Your veterinarian should recheck the glands if the scooting behavior continues more than a couple of days following sac emptying. If left unattended, an abscess can develop in the gland and rupture through the skin of the rectal region. A ruptured anal sac abscess is oftentimes mistaken for rectal bleeding. Anal sac abscesses are generally treated with antibiotics, pain medications and warm compressing the area at home.
Another important reason to have your pet examined by your veterinarian if scooting continues is that there could also be other causes of this behavior such as allergies, parasites or even referred back pain.
What if my pet suffers from anal sac impaction on a regular basis?
If your pet’s anal sacs need to be emptied every month or more, you may opt to have the sacs surgically (and therefore permanently) removed. The procedure can be complicated as the sacs are located next to many important nerves—mainly those that control rectal sphincter function—and meaning, if improperly performed, your pet could permanently loose control of its bowel function. Despite how scary this sounds, anal sac removal is considered a relatively “simple” surgery by experienced surgeons.
While not the most pleasant of topics to cover, I hope you have found this information informative and helpful!

Diagnosis and treatment of marijuana ingestion
Marijuana ingestion is one of the most common toxicities in dogs that I see on an emergency basis, and the post-exam conversation generally starts with the owner asking, "Do you see this often?" I just smile and say, "Well, this is Berkeley..."
Pets are most frequently exposed to marijuana when they ingest “tasty” baked products, eat the remains of marijuana cigarettes, or get into somebody’s “stash.” Dogs can also get into mischief while out on hikes, finding and eating some abandoned drug.
What is marijuana toxicity?
Marijuana is the dried leaves and flowers from the hemp plant (Cannabis sativa) and the active chemical is tetrahydrocannabinol (THC). THC is absorbed quickly into the bloodstream and signs of intoxication can be seen from within minutes up to 3 hours after exposure. The drug is eliminated quite quickly from the body and most pets will make a full recovery within 24 hours. However, mild clinical signs can last for up to three to four days because the chemical is absorbed into fat.
How is it diagnosed?
THC can be detected in blood or urine but diagnosis is generally based on unmistakable clinical signs as well as history from the owner. The signs are quite textbook, and this is such a common occurrence that our receptionists have learned to pick them out, bringing these pets to the treatment area saying, "looks like we have another pot dog." I myself treat several of these toxicities a month.
More than 95 percent of the veterinary patients seen for marijuana ingestion are dogs, and almost all exposed animals will exhibit neurological signs. The most common clinical signs we see are incoordination, urine dribbling, drooling, low body temperature and an increased response to stimulation. At higher doses, dogs can suffer from hallucinations with barking or agitation. Seizures, low or high heart rates, respiratory depression and possible progression to a coma can also occur.
How is it treated?
If a pet has recently ingested the marijuana (within 30 minutes) your veterinarian can attempt to induce vomiting to minimize the amount of toxin available to be absorbed. However, if it has been longer than 30 minutes since ingestion, the anti-nausea effects of marijuana usually make it an unsuccessful attempt.
Your veterinarian may also elect to administer activated charcoal, which will help reduce the amount of THC absorbed. Subcutaneous fluids are often given to help prevent dehydration during the recovery period.
If clinical signs are severe, the need for supportive care will be indicated and your pet may need to be hospitalized. Supportive care entails intravenous fluids, repeat administration of activated charcoal, general nursing care, and observation of temperature, heart rate and breathing. If higher doses are ingested, some animals require sedation with valium, and in very rare cases, may require mechanical assistance with breathing if respiration is severely depressed. This is uncommon, but I have personally treated one patient who required ventilator support (he went on to make a full recovery).
Will my pet recover?
Even in extreme cases, the vast majority of animals recover fully and death very rarely occurs.
The main take-away here: Do not withhold information from your veterinarian if you suspect or know that your dog may have ingested marijuana—even if you think that there is no possible way your pet could have gotten into it. Your veterinarian is not under any obligation to report these events, and this information is needed to appropriately treat your pet, as well as avoid unnecessary (and expensive) diagnostic tests.
