You dog may suffer from loose stools or diarrhea for many reasons, including some serious canine viruses or disorders. Usually loose stools result from eating something that disagrees with the dog's digestive system. For an occasional bout of diarrhea, you may be able to help your dog by offering soothing foods. However, if the diarrhea is severe and lasts longer than 24 hours or if it is accompanied by a fever, excessive thirst or abdominal pain, contact your veterinarian.
Introduce your pooch to fiber. Dietary psyllium fiber, such as Metamucil, absorbs excess liquid in the digestive system and it may help firm up your dog's stool. Offer approximately ½ tsp. per every 15 lb. of dog weight.
Canned pumpkin puree, the unseasoned, sugar-free kind, offers a natural way to provide dietary fiber and most dogs like the taste. Mix at the ratio of 1 part pumpkin to 1 part dog food or offer it full strength to your dog until he passes solid stools for at least a day. After that, you can gradually wean him off the pumpkin and back onto his regular dog food.
Tame your dog's diet with mild food choices until it has a solid bowel movement. Once your dog's digestive system is upset, loose stools may continue, even after the bad food passes through. Switch your dog to a temporary diet of boiled ground beef or boiled ground chicken breast, mixed with cooked white rice. Gradually reduce this mixture and add his own food until he's eating his regular diet again.
Keep your dog hydrated. Diarrhea can lead to dehydration, so offer your dog plenty of fresh water while he's on the mend. You may also pour a little Gatorade into your dog's water bowl to replace depleted minerals and electrolytes lost through diarrhea.
Omit milk and dairy products from your dog's diet, at least for a few days. Some dogs find it difficult to digest the lactose in cow's milk. If your dog's stools firm up after he quits drinking milk, he's probably better off without it, even if he enjoys the taste.
