Pet's info: Dog | Jack Russell Terrier | Female | 39 lbs
hi, i have a jack Russel tilly and she is gaining weight rapidly, she is having shortness of breath and also excessively drinking water. Sadly Tilly is old and has a tumour on her ear, she has been to the vet about this problem. I cant take her to the vet because i am old and unwell, I believe she could have cushings disease as all the symptoms match. I was going to order some vetoryl online but i am unsure and need advice. Thanks

Poor Neneh! I'm sorry to hear that she's having this problem. Based on your description, I would say she definitely needs an ACTH stim test to check her cortisol levels - occasionally, cortisol can drop to dangerously low levels after starting Vetoryl or other medications for Cushing's disease, even at normal medication doses. It's also possible that her current illness is something entirely unrelated, so general lab work and a good physical exam are also important to get a full picture of what's going on.
If she does have low cortisol levels, this can usually be corrected with IV fluids and a short-term course of steroids. Her Vetoryl can then be restarted later on at a lower dose.
