Vet Advice: Treating Your Dog's Diarrhea


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 pounds of body weight, two to three times daily (this translates into 0.1 mg per pound).

Hi Pat,

Considering the age of your puppy I'd say, from experience now, better to be safe than sorry. I hope she feels better.

Can a dog's death be caused by stopping probiotics? My dog had off-and-on GI problems. For over a year, the veterinarian would occasionally prescribe probiotics. For two months my basset hound mix was doing well on the probiotics but I thought since he was on I/D low fat dog food that I could remove the supplement from his diet. Two weeks after I stopped, he started to have diarrhea again. I immediately restarted the probiotics, increased his prednisone to 10mg/day, provided immodium, and put him on a chicken and rice diet. 10 days after the diarrhea started, he was in so much pain I took him to the Emergency Veterinarian. Within 2 days they diagnosed him with pyothorax. Two days after that he died from cardiac arrest when taken out to go to the bathroom. What happened?

I'm afraid I have no idea but I just wanted to say how sorry I am for your loss. I can see how raw and painful it is from your posts and I can imagine how frustrating it is to now know what happened. It sounds like you did a lot to care for your dog and try to find the problem, please don't blame yourself.
Take care

thank you our little cupcake is 9 weeks old and some of the children from our child care gave her human food and she has had diarrhea since then. I will try the rice water and the carrot, are the carrots raw or cooked?

This worked great! However, just a note that 1 cup of rice and 4 cups of water boils down very quickly, so put it on a low boil...and there is actually only about 1 cup of rice water that is distilled from that. It doesn't make a LOT of rice water. I mixed the rice with 1 tsp of baby food and then added a little rice water to make it soupy and she lapped it up. I also have digestive enzymes that is powder form (for my cat, but there also good for dogs from my local pet store) and added a small amount of that to the rice. She has stabilized after a horrible day yesterday. I also gave her a tablet of acidophilus. I may give her some plain chicken tonight with rice. Thank you for the great article!

Thank you for the excellent remarks and advice! I board little dogs, and sometimes they get diarrea when they visit me, because they're out of their normal environment and maybe nervous or scared. I'll try the rice water and the recommended amount of immodium if needed. THANKS!

My 5 year old boxer recently developed Diarrhea. I took him outside and it came out brown then as he kept squatting it was mixing with blood. He did go in the house while I was sleep it was all over his room floor. I saw the food he was fed the day before in the stool. It was a dark brown color, ALMOST black. I rubbed his belly and he seems fine with it. He's still energetic (to an extent). He is sleeping a little more than he usually does. Shall I try the rice and peptobismol???

Submitted by Ezmereka | December 28 2013 |

If blood is mixing in the stool, it is usually very important you get with a vet A.S.A.P.

Same as if your stool was bloody. This is almost always a sign of some serious internal problems.
Sorry your puppy is sick.

My 10 lb Maltese mix has had diarrhea for 16 hours now. She does not feel bad or have a belly ache and still has a good appetite. I had an allergy swab test done on her 6 months ago as she had a limited diet then and still was itching. It turned out she was allergic to so many things I was feeding her thinking they were healthy foods including rice, carrots, pumpkin and more. Once I stopped those, her severe itching was TOTALLY gone. So now due to her diarrhea, I don't know what to give her. I gave her Imodium a year ago and she threw it up so that's not an option either. Help...

My 3-month old puppy is having diarrhea and it has blood in it. He just started this morning and he already vomitted 3 times. We took him to the vet and put him on meds. He doesn't have a problem with eating and he seems to be fine. He's not dehydrated too. Will he be okay?

I am worried about my 7 month old jack Russell I have read the page but I'm still stuck. He is eating fine not lethargic acting his usual self. He hasn't got firm stools but there is a slight bit of fresh red blood I have just give him white rice and also he keeps dragging his bum along the ground is there anything serious to worry about can you tell me anything I must do thank you

If he's rubbing his bum along the ground it sounds like worms

Quite possible that the anal glands are full and need to be expressed. You can do this yourself. A firm stool causes them to be released when defecating.

I have a husky, malamute, wolf mix dog that has terrible anxiety when ANY type of change occurs. The result of her anxiety manifests itself as diarrhea quite frequently. We have tried grain-free diets, roasted chicken, hamburger meat, meds of all types given by our vet, etc. She also often has fowl-smelling gas prior to the diarrhea. We have tried giving her all natural dog food with pumpkin and sweet potatoes to no avail. She is also a very picky eater. HELP

Submitted by Eva | February 3 2014 |

for anxiety there are some natural/homeopathic options:
1) Griffonia capsules 2x a day one.
2) Bach remedies "rescue"
3) a nest scent diffuser, available in larger pet stores. You plug them in in the electrical outlet in the room he/she spends most of their time.
As for behavioral changes. Try and ignore paying obvious attention to it when it occurs. "feeling" with the dog reinforces the idea that there s a reason to be anxious. Be steady and calm.

I just did some rice water, following the directions above. Once boiling, I turned the heat down to simmer - after just 15 minutes the rice had absorbed nearly all the water. There was probably no more than about half a cupful! So I filled the pan up with water again and am continuing to simmer. One cup of white rice doesn't make 'a lot of rice water', I'm afraid! But I will keep trying...

I'm dealing with a dog that gets diarrhea with a sudden change in diet. Slow gradual introduction is important. Trying different , non-cheapo , kibbles and supplementing with never cooked chicken guts , drumsticks , and eggs. All are one third the cost of quality kibbles at $1/pound.

I gave her a quarter of an Imodiem also just a few minutes. We are on vacation so trying to decide if I should find a Vet in the morning. Any thoughts?

I just got a puppy and switched her food.... I was unaware that it should be done in a process because I got the same food the breeder told me to get. She has been eating the new food for 3 days now and her poop slowly started turning into diarrhea yesterday and she still has it. Should I just wait for it to pass or switch her to boiled rice and chicken until her digestive system settles

I recently got a 6 month old puppy from a local shelter to be a companion to my 4 year old. A few days after the guy's arrival, I noticed that both the dogs now have diarrhea. It has lasted about a week now. But it's sporadic. Sometimes their stools are normal and sometimes they are very runny. The odor is horrible, but I don't notice any discoloration or blood in the stool. Also this is the only symptom they present, so I don't think it would be anything more serious (ie. Parvo) but it's odd to me that as soon as a new dog comes home, both he and my other dog now have this diarrhea. I'm still giving both dogs the same food (Blue Buffalo) that I have been giving them all along. Any tips/advice is greatly appreciated.

I have a 6 years old west highland white terrier and he's having a diarrhea. I give him kaopectate last night and this morning it's not helping can somebody give me a good advice to prevent him having diarrhea? Florence of Reno, Nevada

My dog is 15. She is on multiple medications which has caused gas. Up to this point she has not had any change in her bowl movement. This morning she was constipated; it took a long time with a lot of struggle to have a bowl movement. She seemed fine after and I kept a close eye on her. This evening she is very uncomfortable with diarrhea. It is late Friday evening so I am boiling rice to see if it will help. I am hesitant about giving her pepto or Imodium. Of course I will contact her vet if persists but I'm looking for ideas to help her not have the belly ache. It's going to be a long night. She is a small poodle mix.

Hi there, love your magazine! I'm a researcher in dog cognition, and also a collie breeder...your article mentions that caution should be used when giving collies immodium. In fact, collies should NEVER be given immodium, unless they have received genetic testing to determine that they are not ivermectin sensitive (this testing is relatively new and so most dogs have not been tested). If a collie is homozygous for the deletion mutation in the MDR1 gene (which makes them sensitive to ivermectin as well several other medications, including immodium), the animal can become very sick or die. Other breeds (Australian Shepherds, Shelties, Border Collies, and Old English Sheepdogs) have similar sensitivities. I just thought this deserved to be clarified, as pet dog owners with these breeds don't always know that the sensitivity extends beyond just ivermectin, and they should be aware that a collie or any other ivermectin sensitive breed can have very serious reactions to immodium. I've seen it happen, but fortunately the dog was only given a low dose, and she was ok.

Just a thought--maybe you could do an article on ivermectin sensitivity in dogs?
