Aloha! You're speaking to Dr. Michael SalkinI understand your reticence. I guess I'll have to be the bearer of bad tidings. When such a 14 year old loses a significant amount of weight and has halitosis yet eats quite well, I have to be concerned that he's now diabetic as well as Cushingoid. The breath of these dogs can smell like acetone (some brands of nail polish remover) if the diabetes has progressed to a diabetic ketoacidosis - a severe form of diabetes which needs prompt attention.A 14 years of age there are usually concomitant disorders to consider. In particular, Sam's kidneys need to be checked carefully because a chronic renal insufficiency is likely when weight loss and halitosis is present. Dogs with kidney failure, however, rarely continue to eat well so either his kidneys aren't failing or his Cushing's is keeping him eating in spite of kidney failure arising. In any event, I want Sam to be seen prior to his usual visit planned for 4 weeks from now. When a cushingoid dog loses weight we're going to find that more than Cushing's is present. Please respond with further questions or concerns if you wish.
Thankyou for your advice I will take sam to the vets tomorrow.
