Rest the stomach - It is perfectly normal for dogs to self regulate and occasionally skip a meal. If your dog is generally healthy with no underlying medical conditions, and is vomiting or experiencing diarrhea, give your dog’s stomach a rest and allow him to skip a meal. Provide access to fresh water -While your dog isn’t eating, make sure there is plenty of access to water to prevent dehydration. A little pepto bismol or imodium may also help (dose according to your dog’s weight). After your pet’s missed meal, try to stimulate his appetite by offering a bland sick diet for dogs like homemade chicken and rice (substitute the brown rice in this recipe for White Rice because it is easier on digestion). We understand how challenging it can be for pet parents to know what to feed a sick dog with an upset stomach keeping the diet simple will help. Dogs have an incredible sense of smell and typically the aroma of a home cooked meal alone will be enough to get a dog who wasn’t eating previously to start nibbling again. Make sure the food is cool to the touch prior to serving, and not hot.
