What Are the Side Effects of Benadryl in Canines?
Benadryl, name brand diphenhydramine, is an antihistamine. Primarily used for allergies and inflammation, it also treats anxiety and vertigo. According to Vetinfo.com, the recommended dose for a dog is 1 mg per pound of body weight. Benadryl isn't recommended for dogs with glaucoma, hyperthyroidism, cardiovascular disease, lung disease or prostate enlargement. Use plain Benadryl; diphenhydramine is the active ingredient. Products containing acetaminophen (Tylenol) cause liver damage and possibly death. Some types contain alcohol, which also cause liver damage.

Dogs might experience nausea and vomiting after a dose of Benadryl. The symptoms cease shortly after medication is stopped, if not before then. Dogs also might have diarrhea and decreased appetite.
