A dog or cat with diabetes is like having a baby with diabetes? But more of a hands off approach. It's just pets can't tell you they don't feel right and their care is totally in your hands. She has gone way down in insulin usage with the bad teeth pulled so that was a few sleepless nights as we reduced her doses. She is now staying more stable.
There's exercise playing with our other dog etc, (lowers) plus a foot she decided to chew on (grass allergy, raises) The vet she has now is delighted with her figures, but I'm not completely. I want it nudged down some still. I am the one that does all the adjusting as needed.
Yes we do rely on the Libre to dose, we still do some blood sticks to know the accuracy or if in doubt. But when you see a reading on the Libre of 304 I know she needs 2 units. Your aim is for below 200, (I like to aim for 150) so when it is off by 20-40 points it really doesn't matter. 1 unit of Humalog can lower her BG 50-75 points. That had to be found out by using it as most people or vets don't use Humalog on their pets. They just use the Novolin type insulins.
