Is my dog's excessive drinking and peeing normal after Addison's steroids?

Updated On September 23rd, 2025

Pet's info: Dog | Bull Terrier | Male | neutered

Hi my dog has really recently been diagnosed with addisons disease. After having a Crisis last week and being stabilised in hospital. We had the test and it was confirmed. He is full of steroids obviously. He had his first treatment on monday injection followed by the daily pill. It is his second day now.. I know it is normal for him to drink alot and go to the toilet with the steroids in his system. But he is drinking so much and goes to toilet once an hour all night all day. Is this expected?

That is expected with a high dose of steroids, however if it is a concerning amount I would let your vet know. They may want to adjust his steroid dosage, or otherwise monitor his side effects from it to see if additional treatment or changes need to be made.

    Increased thirst and increased urination is a very common side effect of steroids. Some dogs are more sensitive to the side effects than others. Decreasing the dose may make this go away, but may not treat the condition your vet is concerned with. I would contact your vet about the side effects and get their guidance on switching or stopping the steroid. Steroids are usually tapered off rather than stopping cold-turkey.
