I've got a cat with Diabetes - he's currently on a low-carb all moist-food diet and gets twice daily injections human-grade Lantus versus Vetsulin or another pet-formulated insulin. We also test his blood sugar at home using a regular glucose meter for humans. There's a huge feline diabetes message board with thousands of members - not sure if there's one for dogs but it would be worth looking into. If nothing else if you google feline diabetes message board you'll find the cat one and you could post on the Community section looking for dog owners to give you advice. Right now a LOT of cats are getting off insulin if they're treated quickly with Lantus versus Vetsulin etc. As for diet - cats are obligate carnivores so an all-moist wet-food, high protein low carb (under 10% of calories from carbs) diet works really well for diabetic cats and can make many of them diet-controlled. There may be a similiar diet for dogs out there if you look around. Be proactive - don't just do what your vet says. If I'd obeyed my original vet my cat would be dead - instead he might well be off the insulin and diet controlled by Christmas. At the very least he's much better now that I found a vet who will work with me and use the newer treatment options like Lantus.

One other thing to know - There's an FDA advisory about Vetsulin right now, there have recently been some batches that are "less effective" and imo should have been recalled but haven't yet. Its JUST happened and barely hit the news.
