We found a lost dog two days ago. The dog is very calm and well-behaved, but he has diarrhea. He doesn't drink a lot of water, and hardly eats any food. He's a medium-sized dog, mixed, with long white/tan shagged hair.
This dog should be seen by a vet. It may have gastroenteritis. This could be bacterial, parasitic, viral etc.. Bring a stool sample tp the vet. Try a dose of pepto bismol and a bland diet of boiled chicken and rice until you can get to the vet. vetcare
