I am a little confused by this book. I am a Type 1 Diabetic in desperate need of a service dog. I've applied for one (14 months ago) and have been researching it for over 2 years.
That being said, this book has a few errors. Maybe not errors, because I cannot swear by the accuracy of my research, but my info comes from the leading dogs-for-diabetic agencies in the US as of 2019.
I've been taught, the best dogs to truly smell BG fluctuations are larger dogs - specifically labs and retrievers. Also, the book says the dog was sleeping on a pillow on the protagonist's bed and/or chest. Ah, no. Scent travels like pouring water. So diabetic dogs have to sleep on the floor next to the diabetic. Otherwise nightime BG changes are less likely to be detected. It doesn't matter how much the dog wants to sleep with or near you, you CANNOT acquiesce. It's your life on the line. Literally.
I'm not trying to nitpick over details, but since I'm applying for a dog I want to know every tidbit of info I can. Many families pay over 30K for a dog, because that is how much it costs to train one.
I needed an emergency glucagon shot less than 4 hours ago, which saved my life. If I had a dog, my life would be so different. I'm reviewing 4 stars because I so much appreciate the author for shining light on a real problem!!! And I enjoyed the book :)
