I have always been curious about hypoglycemic dogs..
I am Diabetic.. I experience hypoglycemia often.. It will cause symptoms just like what that dog is showing.
I have a glucometer.. It is a device that will read a very small drop of blood (Finger stick with a needle),and tell me my blood sugar level. It takes 5 seconds...
The prick with a needle is absolutely painless..
I have always wondered if Dogs blood can be read through something like this.?
It would immediately tell you the next time the dog is symptomatic. You would only have to prick his skin,and get a small drop of blood.. and put it on a test strip, insert in reader..
I have also been told,,, that ingestion of engine antifreeze can cause glycemic level to be low..
I hope your dog gets better.... It really sucks when they are sick.. Good thoughts sent your way..
