"Simple" diarrhea can frequently be managed at home by withholding food for 12-24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet (1:1 ratio of plain boiled boneless chicken and plain white rice). Feed in small, frequent amounts waiting at least one hour between feedings. Continue feeding until the stool is normal. Transition slowly to the regular diet. If the diarrhea doesn’t stop or other symptoms (vomiting, lethargy, loss of appetite, etc.) develop, see your veterinarian.

withhold food for 12 hours then offer her boiled boneless chicken and rice every 6 hours in small portions. if she is eating and not vomiting, continue with this diet for 2 days. After 2 days, you can put her back gradually on her normal food. If she continues having diarrhea, take her to the vet to get treatment.

As long as your dog isn't vomiting and is not lethargic, its reasonable to try to treat at home. If he or she is vomiing or seems lethargic/dumpy or is not eating at all, please take him or her to the vet. To treat at home, withhold food for about 8 hours (as long as its not a young puppy less than 3 months old). Then offer boiled chicken and white rice rather than normal dog food, with about 1/2 of a normal meal amount of food. The second day, feed a normal amount but continue chicken and rice for about 3 days. Add a probiotic as well, you can pick up a dog probiotic at any pet store. If its not improving in 3-4 days or he or she stops eating, is vomiting, or becomes lethargic, please take your dog to a vet. Thank you for asking Petco Pet Education Center, formerly Petcoach!

The chicken and rice should be easier to digest and so the stool should be a better quality. The diarrhea could be due to many conditions including eating something he shouldn’t have, bacterial over growth, parasites or other even organ disease. If the diarrhea has continued beyond 24 hours, I recommend to have him examined by the veterinarian. With continued diarrhea, there are often bacterial shifts in the gut that will make matters worse regardless of the initial cause. Make sure to bring in a sample of fresh stool. The doctor will check him for parasites and bacterial over growth. Continue giving the bland diet. I hope Bear gets back to normal quickly. Please feel free to post any additional questions!

Hello, I am sorry to hear about Lucky. Diarrhea can have many different causes in dogs. It can be secondary to problems within the GI tract such as dietary allergies, inflammation, parasites or ingestion of foreign material. It can also be due to systemic problems such as pancreatitis, liver disease, or kidney problems. Since the diarrhea has been going on for a long time and has not improved with a bland diet I would recommend having Lucky evaluated by your veterinarian. They can perform an examination and discuss additional diagnostic workup which could include bloodwork and x-rays. Hope this helps, good luck!
