For those of you who have given your furbaby benadryl did it affect them the same as it does humans. I know when I take them I get really sleepy and grouchy. My vet told me to give Sophie a 25mg tablet for her seasonal allergies. I haven't given her one yet because I am scared to. That seems like such a high dosage even though she is 12lbs. I even called them again to make sure that was the right amount. I would appreciate any advice you could give me. Thanks
