Unfortunately, by law it is illegal for the experts at Petco Pet Education Center, formerly Petcoach to recommend using any human drug, including OTC drugs, without seeing the animal in person first. That's because doing so requires a veterinary client patient relationship which cannot be achieved via an internet forum. In addition, the experts cannot say for certain if a specific drug is safe for your dog. If she is shaking and feels hot, she could have a fever which Benadryl wouldn't treat anyway. I would take her temperature rectally. A dog's normal temperature is 101-102.5F, and if her temperature is above 103F, I would take her into an ER vet or a vet on call immediately. Otherwise, I would monitor her and try to tempt her to eat with some boiled white meat chicken (no bones) and white rice in small amounts several times a day. Should her symptoms continue through until tomorrow, I would have her seen by a vet. If they suddenly become worse or she develops other signs like vomiting and diarrhea, I would have her seen by a vet immediately.
