Oh, I'm sorry to hear about Bandit's diabetes. But as you probably already know, many diabetic dogs and kitties live full and happy lives I've never had a dog with diabetes, but I do have a sugar kitty! After a 2 month course of insulin, he's controlled on special diet alone. I found the diabetic cat online forum to be a great source of info. and support. Fortunately for me, my Mr. B never refused food. I know how important it is for you to be able to balance Bandit's food/insulin dosage. Is he on a special diet, perhaps not to his liking? Has he been a finiky eater in the past? His body chemistry is going through a lot of adjustements too right now and that as well may be affecting his appetite. My advice would be to check back with your vet. And I'm sure those on the diabetic dog site would have a lot of insight on this problem too. I hope all the best for your dear Bandit! I think there are a couple of diabetic dog moms here. Hopefully one will chime in soon! Please give Bandit a big hug for me Sandra
