And it's not a clear indication. I can tell from her behavior when my blood sugar is dropping too fast. I get a bit cranky when my blood sugar drops and she obviously doesn't like it and gets a bit agitated herself. Thus, when she starts acting up, I know it's time to double check.
It's happened at both agility trials, last weekend and this weekend, which is weird, as I tend to run high at trials. Last week, I was running my old pump, and had cranked up the insulin a bit too high. I didn't want to repeat it today, so I left everything along, and I still went low – though I tend to be running a bit low on this pump – not sure why, could be because I'm checking my blood sugar more, and adjusting my blood sugar more.
Will know better next week when I'm back in a regular routine.
