I've never had a dog with diabetes, but a cat, yes. And even though I'm a nurse, there was still a lot to learn about diabetes in cats vs. humans and it was an adjustment to schedule my days around his needs, i.e. insulin injections, blood testing etc. Luckily for me and Mr. B, he converted to a non diabetic state after a couple of months and is now maintained on Rx food alone. (Purina Diabetic Management) He had been on humulin insulin, regular, varying from 4 units, when his BS was at it's high of 700 to 1 unit twice daily. Hope your sugar pup is doing well Sandra
