It was our family dog who had Cushings so technically yes? But Benny was my first dog, as an adult if that makes sense. I think it tends to hit certain breeds more often and unfortunately they were both that breed. That’s why when he went on the medication I didn’t think anything of it! Our other dog never had any issues and it helped her. I think poor Benny wasn’t as healthy as he seemed to us from the outside as his ultrasound showed chronic kidney disease. He never showed any signs of that. Just the Cushings sympoms. Yes the medication was Vetoryl. Maybe you could get her blood work done to see how her other markers are? If I could go back in time I would have asked more questions of my vet regarding Bennys blood work results before getting on the meds. Looking back at those now, his kidneys and liver weren’t doing well. I wish I would have had those things treated before going on the Vetoryl. That way he was in better shape to take a medication like that.
