Hi Kellye P,
I am so sorry to hear about your little guy.
When you say his glucose levels are good can you tell me how often he is tested and what his numbers are please? Has he had a Hemoglobin A1c Test or a Fructosamine test, both of which will show your dog’s average blood sugar over a couple of weeks or months? High blood sugars could interfere with glucose metabolism and cause weight loss.
He is also on thyroid meds and a high thyroid level could also cause weight loss. Does he take thyroid medicine once or twice a day? He should be taking his meds twice a day not once. His thyroxine (T4) levels should be tested about 4 hours after giving him his thyroid medicine and should be high normal to about 25% over normal.
Does he just stop eating after he eats a certain amount of food? Would it be possible for you to feed him 25% more than you are feeding him now?
Please let me know these things so we can all try to figure out how to help your little guy gain some weight.
