Dog has persistent hives
She was bit by a bug last Friday, became lethargic and painful. Took her to the vet and pocus and BP was normqal, gave benadryl inj and pain inj and told to do benadryl 3 times a day. The hives got a bit better, but were almost all over her on Thursday so took her back to the vet on Fri and pocus and BP was normal and so they gave a dexsp inj and said to continue the benadryl and do prednisone. The vet said the hives should be gone by 36 hours, but she still has them. She's not scratching or acting abnormal. Should I be worried? Is it normal that they are still persistenting?
