diabectic dog getting too thin maybe?

Question
I have a 5,5 year shepard with diabetes. He was diagnosed by chance at the vets with another issue. He needs only 8mm twice a day and eat Royal Canin weight control diabetic. He was only a little bit overwieght (2 kilos)...the vet said it is a mystery why he is diabetic. He is now looking very trim and we get compliments by our neighbours. I am just a little worried he might be getting too thin. Otherwise he is healthy and happy. I will be going to the vet soon for his sugar check but I am just cruising the net here and thought I would ask.  ALso sometimes he is very hungry and needs to have a little something or he will vomit up bile. He was always like this since we had him. If he did not eat at night at 5 in the morning I had a 'squeaky' dog. Just curious. thank you

Answer
If he seems to thin then you need to put him on a different diet or increase his food intake. I would feed him twice a day instead of one but just divide his food in half and feed morning and night. That will regulate his sugar better as well.

If your vet doesn't understand that there are many types of diabetes in dogs then you might want to find a new vet. :-)

Dogs get idiopathic diabetes, primary, like people get and even rarely, the kind that humans get called juvenile diabetes. Idiopathic means that there is no obvious cause, such as the pancreas not working.

So weigh him at the vets, adjust his insulin units accordingly and then feed him a cup more of food. Just divide it and feed twice a day as I mentioned.
