Hi I am new here. 10 years ago my wire fox terrier fought adrenal gland cancer after a valiant fight with surgery, chemo and then to find out it had metastisized to the other adrenal gland. Now I have another wire fox terrier from the same breeder who is hypo thyroid and has started similar sxs.....excessive urination and peeing. 2 weeks ago ihad the vet check his glucoxe which was normal. Then I returned him to the vet to test for what I feared....cushings. his ot was normal. Pt was 264 and alk. Phos was 2011. What test should we do next?
