How do 'diabetes dogs' detect low/high levels of insulin?
I recently (well 2 minutes ago) read this article:
I was wondering how do these dogs detect whether someones blood sugar levels are low/high? Also how are they trained?
Another question I wanted to ask is why don’t they just buy a machine to do this. I know dogs are cute and stuff, but surely a machine would be more cost effective?
