Full Answer

Some dogs experience diarrhea when they are excited or under stress, explains petMD. In addition, diarrhea can be a sign of a wide variety of medical issues, such as bacterial or viral infections, internal parasitic infestation, kidney or liver disease, cancer, colitis and hemorrhagic gastroenteritis, according to WebMD.

Treatment of diarrhea in dogs involves identifying and treating the underlying cause, states petMD. If an upset stomach is likely caused by something the dog ate, withholding food for 24 hours is often recommended, indicates PetEducation.com. Dogs should have access to plenty of water to avoid dehydration. Following the 24-hour fast, the dog can eat small amounts of bland foods such as rice, slowly resuming a regular diet as the diarrhea subsides. Veterinary attention is necessary if diarrhea continues.

A veterinarian treats infections with antibiotics or antifungal medications and provides wormers to treat parasitic infestations, states PedEducation.com. In cases of poisoning, the veterinarian may administer medications that slow the transit of matter through the intestines. He may also provide medications to alleviate nausea or treat gastrointestinal inflammation or excessive production of gastric acid, notes petMD.
