This rash appeared on my B about a month ago. 1st vet trip they said to give Zyrtec & Benadryl. That seemed to help the agitation but didn't clear the rash up. 2nd vet trip they prescribed Prednisone & Cephalexin which really decreased the redness & he stopped licking at the rash. Now at the end of this round of treatment he is beginning to lick at it again. I have made an appointment for a skin test but thought I might get some insights from the B community. Thanks in advance guys!!!
