Could my dog's cough be from Benadryl or prednisone for hives?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 60 lbs

My dog had hives from stings. It’s been two days we treated with Benadryl and prednisone. Still has slight bumps but now he is coughing like crazy. It’s worrying me. Could the cough be from those meds. He’s acting really blah as well

I would be concerned that there is still swelling, potentially irritating the trachea or throat if Apollo is also now coughing and the hives haven't resolved after two days of home treatment. If this continues or worsens it would be best to seek veterinary care to have Apollo examined and treated with a strong medication to help stop the allergic reaction, especially if he is having swelling of the face or neck, or is having trouble breathing.
