When used properly, Benadryl, a common brand name for the drug diphenhydramine, is very safe for dogs. However, over the counter versions of Benadryl designed for humans often contains other medications like acetaminophen or pseudophedrine, which can be toxic for dogs.
Benadryl tablets are safe for dogs and generally result in a moderate reduction of stress/anxiety. You can give 1mg per pound that your dog(s) weigh. So for example, if your yorkie weighed 12 pounds, you can give them 1/2 of one 25mg tablet. I would suggest trying it in advance just to ensure that it is effective for your pets. Safe travels!
