Why is my dog peeing a lot on prednisone for Addison's disease?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 4 years and 8 months old | 47 lbs

My dog was recently diagnosed with Addisons and had his first injection of DOCP about 2 weeks ago along with a daily dose of prednisone. I've noticed today that every time he gets up he pees. What is causing this. He is only 3.5 yes old.

Unfortunately this is a symptom of the steroids and you may see this indefinitely if he is on the injection and oral prednisone. It may be possible to taper the prednisone so that all he is receiving is the DOCP injection. I would discuss this with your vet first prior to adjusting the dose yourself though as you do not want to cause him to go into an addisonian crisis by dropping the steroid dose too much. I hope this helps! Please let me know if you have any other questions or concerns. I am also available via consultation if needed.
