Recently my 8 year old Pomeranian was diagnosed with Diabetes. Broke my heart. How ironic too since It came and got me one time when my mom went into a Diabetic Coma..
anyway, Glad to hear she is doing well!
We feed skipper a special W/D Diet and he has 3.5 units of insulin 3times a day. At 7am-3pm and 11pm. Quite a handful, but we love that dog so much.
Make sure she drinks lots of water, goes to the bathroom enough, doesnt sleep all the time, and gets lots of exercise!
Best of luck!
I don't know anything about canine diabetes, but I would think if shes improved, the water drinking would have too. Click on Forums on top of this page, and scroll down to Pets, click on Ask a Vet. Maybe they can give you more info, good luck.
