I wanted to ask a question about hives and prednisone. My 5 month old boxer pup came in yesterday with a swollen face and hives. We assumed he had gotten stung by some sort of bug. We had to take him to the emergency vet because he seemed to passout and urninated on himself. The vet gave him a shot of Benadryl and cortisone. His swelling has gone down but we had to make another visit earlier this morning because the hives came back in such big patches. The vet sent us home with prednisone but also a lot of warnings. We have just been treating him with the Benadryl 1mg per pound he is 38 pounds.
He seems to be hot always seeking non carpeted surfaces. He also seems to act like he is losing his mind at times. Do you have any suggestions? Should we go ahead and use the prednisone or is it that dangerous? I really appreciate any help you can offer.
I don't know anyone else to ask and our vet will not open until tomorrow.
