Hi there! Normally, if a dog being treated for Cushing's disease is still drinking and urinating excessively, this is an indication that her Vetoryl dose may need to be adjusted. We calculate a starting dose based on weight, but many dogs need further adjustments from there depending on how they respond to the medication. I would recommend calling your vet to discuss this. He/she will likely recommend bringing Ali back in for an ACTH stim test to check her cortisol levels, which will help guide the decision about whether to change her Vetoryl dose.
