Tonee (RB) had cushings. She was treated for 2.5 years before she left us. She had it for several years before bing diagnosed with it. She was treated for air way, bronchial tubes constrictsion. She never had this problem, just miss diagnosed for several years. You need to get blood work done, full set and liver panel too. The emergency vet could tell by looking at her that she was 'cushingoid' our regular vet could not and sent her home on anti-inflamatory meds, ( we had gone to reg. vet for a torn ligament originally)which is what led us to the emergeny vet it the first place. Tonee did not have sores. Her signs were panting while at rest, bloated or enlarged chest area, thinning hair and after the anti-inflamatory meds, which blew up her gut, bloody diarrhea. Only the blood work will tell for sure, but if your vet hasn't mentioned cushings, ASK him.
I miss my Tonee EVERY day, her birthday was December 18th !!
