Addressing the second most common problem on the vet hit parade
October 18 2012
Question: Recently, my dog's nighttime scratching is keeping both of us awake. Her fur seems dry and a bit dandruffy, and she also seems to be shedding more than usual. What can I do to help her?
Answer: Dogs itch for many different reasons, and sometimes, for no reason, and it’s not uncommon for the scratching to seem worse at night, when the house is quiet. Every dog’s gotta scratch some time, and that’s completely normal. But when a dog is incessantly licking, scratching, biting and chewing to the point of wounding herself, then scratching becomes a symptom of an underlying pathology.
The medical term for scratching related to excessive itching is pruritus. This is the second most common reason people take their dogs to the vet (gastrointestinal problems such as diarrhea top the list). The causes of pruritus can be quite complex, but there are two main reasons why dogs itch. The first has to do with the condition of the skin itself: Is it infected? Is it too oily? Is it too dry? Of these three, dry skin is a frequent occurrence. The second major cause of pruritus is allergies.
Is It Dry Skin?
Dry skin can be influenced not only by environmental factors, but also by diet. Commercial pet foods process out the good oils that contribute to healthy skin and a lustrous haircoat. Dry pet foods have an even more dehydrating effect on skin and hair and also stimulate increased thirst, which only partially compensates for the drying nature of these diets.
If you must feed dry foods, then by all means add digestive enzymes to your dog’s meals. In fact, digestive enzymes are good to use with any type of food. Enzymes improve the release of nutrients, and beneficial probiotic bacteria also assist in the digestive process. (Probiotics also help with allergies, as noted below.) A healthy digestive system absorbs fluids more readily from the food your dog eats, thus improving hydration and increasing the moisture levels of the skin and haircoat.
Whatever the cause, allergies are difficult to address. In the worst cases, afflicted dogs require strong (and potentially toxic) pharmaceuticals just to get some relief. Though allergies are rarely cured, early identification and intervention can keep them under control, and in some cases, can substantially diminish them.
Clinical research has shown that one important way to reduce the likelihood that dogs will develop allergies is to give them high-potency cultures of beneficial probiotic bacteria such as Lactobacillus acidophilus and Lactobacillus bifidus when they are very young. Probiotics are relatively inexpensive, absolutely safe to use, and can save both dog and the owner tons of grief—and visits to the vet—later in life.
Regardless of age, many dogs’ allergies are controlled by improving the quality of their diet, giving them high potency acidophilus cultures and high doses of fish oils; adding freshly milled flax seed; and, in some cases, giving them antihistamines. (It can take up to three months for this regimen to take effect; see sidebar for details and dosages.)
Determining which condition your dog is dealing with requires a vet’s evaluation, but implementing some of the suggestions provided in the sidebar can certainly help your pup be more comfortable in her own skin—literally.

Common canine ailment responds to home care and familiar remedies

Question: Help! my dog has diarrhea—is there anything in my medicine cabinet or on my kitchen shelf that could be used to save both of us a visit to the vet?
Answer: As a veterinarian, this author sees many patients with minor problems (such as the dog in this story) who could be treated at home safely and effectively. At the same time, there are dogs whose problems, if not addressed early enough by a veterinary professional, suffer more than they need to.
Probably the most common complaint received by veterinarians is that of diarrhea. It’s such an easy condition to identify: The smell is unmistakable, as is its chocolate-pudding appearance. Most of the time, diarrhea is caused by a dietary indiscretion or stressful circumstances, and is self-limiting. Diarrhea is not a disease; rather, it is a symptom of a dysfunction of the gastrointestinal tract (GIT). When associated with bad food or food-borne pathogens, diarrhea serves to rapidly remove pathogens from the GIT before they have a chance to be absorbed and cause more damage.
Warning Signs That Diarrhea Needs Medical Attention
• Loss of appetite
• Marked lethargy
• Frequent vomiting
• Signs of abdominal pain (bloating, groaning, panting rapidly or avoidance response when belly is touched)
• Lasts longer than 48 hours (Since it can rapidly weaken puppies and geriatrics, or dogs with chronic diseases, they may need veterinary attention sooner.)
However, when your dog has mild diarrhea and doesn’t meet any of the above criteria, the best things to start with are a 24-hour rice-water fast; white rice balls that contain active probiotic cultures; and the oral administration of an intestinal protectant such as kaolin clay and pectin (KaoPectate™) or a suspension containing bismuth subsalicylate (PeptoBismol™). Loperamide (Imodium™) can be given if the diarrhea doesn’t resolve easily; caution is required when using this OTC medication in Collies, and don’t use it for more than five days. (Another caveat: While dogs can tolerate PeptoBismol or KaoPectate, these medications should never be given to cats, as they contain salicylates, which are potentially toxic for felines.)
Fasting your dog allows her GIT to rest and recover from whatever insult it has received. During the fast, make sure she has plenty of rice water to drink. Rice water is the creamy liquid that results from boiling white rice in water. It’s important to use a good quality white rice; “minute” rice does not work and brown rice has too much fiber in it, which does not help firm the stool because it speeds the transit of digested material through the colon.
To make rice water, boil one cup of white rice in four cups of water for 20 to 30 minutes (depending on your altitude) or until the water turns creamy white. Decant the liquid and allow it to cool. You can serve the rice water to your dog as often as she will drink it. If she isn’t interested, mix a teaspoon of chicken baby food (or another flavor that your pet likes) in the rice water to increase its palatability. (Hint: One cup of white rice makes a lot of rice water!)
Probiotics—living bacterial cultures intended to assist the body’s naturally occurring gut flora in reestablishing themselves—may also help speed recovery. These live microorganisms are found in yogurt, for example, and are also available from your health food store or your veterinarian as high-potency powdered acidophilus cultures, which are more effective than yogurt for diarrhea. Mix these cultures into the rice water that you are serving your pet during its fast.
After the fast is over, start your dog back on a bland diet of white rice cooked with extra water and mixed with small amounts of baby food for protein and flavor; for each cup of dry rice, use two to three cups of water. Continue to add probiotics to her food, using at least 2 to10 billion viable bacterial organisms in each meal you serve; to determine the level of “viable organisms” or “colony forming units” (CFUs) present in a probiotic such as acidophilus, look on the label—a reputable manufacturer will list that number.
Dosages for the two intestinal protectants mentioned above are approximate. Use the liquid medication, not the tablets, and give about 1cc of liquid for each 10 pounds of body weight up to three times daily. The bismuth subsalicylate has more anti-inflammatory activity, so may work better on patients with abdominal cramping.
If the diarrhea is very severe, you may want to also give your dog some loperamide (Imodium AD™), which can help to reduce fluid loss until the rice-water fast, white rice and acidophilus, and the dog’s own healing system can overcome the diarrhea. The published dose for loperamide in dogs is 2 mg (the standard-size capsule) for each 40 - 45 pounds of body weight, two to three times daily (this translates into no more than 0.1 mg per pound).
