My dog scratches on prednisone. Could it be allergies or mange?

Updated On September 23rd, 2025

Pet's info: Dog | Miniature Schnauzer | Male | neutered | 11 years and 4 months old | 21 lbs

My min schnauzer has Addison's disease. I give him monthly injections of Percorten, feed him dog food for sensitive skin and stomach, .25 mg prednisone every day, has no fleas...but he is scratching terribly. Could he have allergies?

I would be more suspicious of mange. Mange is caused by a microscopic mite that can thrive on dogs receiving prednisone regularly. This causes them to be very itchy. Allergies are still possible, but the prednisone would normally mask the signs of allergies and it would be rare for him to still be itchy. It's best to take Noah to the vet for an exam. They can check for mange and prescribe treatment if needed. I hope that helps and Noah gets better soon.
