Let your dog take a 24 hour break when he has upset stomach. After that give him some boil rice and skinless chicken. Yogurt and cottage cheese will help the inflamed intestines. You can also mix Gatorade into the dog’s water bowl. Animals, unlike humans stop drinking when they feel sick. You need to do everything in your power to avoid dehydration. Some symptoms of upset stomach are lethargy, vomiting, persisting high fever*, increased thirst, abdominal pain, constipation, and loss of appetite. If your dog remains sick and refuses to drink fluids a trip to the vet might be your last option. Most dogs overeat and like eating rubbish. They have no idea of what tastes good or bad. They just try everything they find on their way. Dogs have a less developed sense of taste. However, their sense of smell is more developed than humans. They can get a lot of information through their sense of smell. Dogs are meat lovers. However, they can’t make a difference between the different types of meat. If your dog eats pork there is a risk of your dog being infected with food borne disease called trichinellosis. This disease is caused by an intestinal roundworm. Trichinellosis isn’t that common in USA. Your dog should be fine if you avoid raw or undercooked meat. Nevertheless, chocolate, onions, caffeine, raw eggs, wild mushrooms, raw fish, fried food, cornmeal, and nutmeg will also make your doggie’s stomach upset.
