Snowy had diabetes 3 years ago, but went into remission. His diabetes is back and I am having an impossible time, with not much help from my vet! His BG was 556 when I took him to vet. Started off with 1 unit twice a day, kept moving up to 2 1/2 units twice a day. His numbers are bouncing all over the place. 2 1/2 is too much, I had to cut it back to 2 because I had to skip shots because numbers were low, then of course with no shot the next BG reading was very high. Vet had me giving many different amounts of insulin depending on what each BG test was. From 1/2 to 2 1/2, he wanted me to go to three but I refused! I decided to just stick to 2 units for awhile unless it dips too low. His numbers have been bouncing all over the place, from 129 to around 500. I know you can't use Lantus the way he's asking me to. Can someone offer some guidance?
