Updated On September 23rd, 2025

Pet's info: Dog | Bichon Frise | Female | spayed | 11 years and 3 months old | 21 lbs

If a dog has tested negative for Cushings disease, do they need to be tested again? The tests were several years ago. Thank you.

I would recommend it if she were showing signs. Though she wasn't years ago, she could be now. Signs include increased thirst, increased urination, increased appetite, a pot belly appearance and panting. I hope this helps!

    Hi there. Cushing's disease can be difficult to diagnose in some cases, unfortunately. I would agree that Kelly's symptoms sound very suspicious for this problem, so it would be a good idea to pursue additional testing to try and get a diagnosis, if you can. If the initial blood test (probably a low-dose dexamethasone test?) was normal or inconclusive, then you could consider an ACTH stim test (a different type of blood test), a urine cortisol/creatinine ratio, or an abdominal ultrasound as the next logical step. I usually use the ACTH stim test as my second test if the low-dose dex test is negative and we're still suspicious, but an ultrasound would also be reasonable as the second test if your vet is skilled at doing this.
