Default Re: Annie needs help

Craig - welcome to you and Annie. I'm glad you joined us.

Indeed, I think those numbers you show suggest the possibility of rebound, as Natalie suggested.

I notice you take readings at fasting-time - just before feeding. What about BG curves? - taking readings every couple of hours, for at least 12 hours (some do 24-hours, but I don't bother, as my dog, Kumbi, seems okay overnight).

Does your vet, or do you, at times, take curves?

I have a bunch of charts on my web site, some of which show rebound, or rebound-like, effects. If you start here, you can go through various charts by using the NEXT buttons above the main pictures on each page.

There are other charts on the web, also.

I think charts help to show what's going on, especially for visually-oriented humans! (me, for instance; haha!)

Another thought I had, though this would really take some work, is that, Annie, being fairly small at 16 pounds, might do well on NPH insulin, which has only one peak (time of most-intense working), rather than the two that Vetsulin has. The first, and heaviest, Vetsulin peak occurs so-many-hours (perhaps 4 to 6) after injection; it's the faster-acting component of Vetsuilin that does that; then a second peak comes along maybe, say, 11 to 14 hours after injection. This second peak would be a gentler one than the first. (My indication of timing is from memory, and may not be perfectly accurate; also, timing of the peaks varies with individual dogs.)

But without curve data, we can't really see anything about how BG levels are varying throughout the day (nor, of course, the night).

If you or your vet does curves fairly regularly, perhaps you could post some curve-numbers? And if not, I would certainly do a curve as soon as you conveniently can. If you do it, of course, you'd need to be home to do it! A curve, though, would help reveal whether rebound is in fact occurring.

Changing insulins is a job and a half, not to be undertaken lightly, and I wouldn't even raise the issue if Annie were going along really smoothly.

But if you think you might like to change, the aim would be to flatten the response to the insulin, between injections. Once a dog is well-stabilized on NPH insulin, too, the need for constant testing seems to be reduced, as long as there aren't other underlying conditions besides diabetes.

I always defer to the observations of Natalie and Kathy on this forum, so I'd certainly attend to what either has to say about Annie.

So many dogs (by no means all) do well on the human (NPH) insulins.

Vetsulin, or its counterpart elsewhere, Caninsulin), seems to do a really good job for a lot of dogs - but then, so does Novolin-NPH, or Humulin-NPH (or similar insulins) - for many dogs.

My Kumbi, who weighs about 20 pounds (right now, 19 pounds), does really well on Novolin-NPH, and he's been on that from the time of his diagnosis, 1 September, 2006.

Welcome! I'll be following Annie's story.
