i am trying to give my 4 yr old a haircut. his groomer is booked & he has got to be trimmed. he gets a little nervous so the vet had told me before that i could give him benadryl, i just cant remember how much & cant get in touch with his vet. he is 4 yrs old, 5 lbs now. has no health problems. should i give it to him? if so, how much?
