Dogs: What's the secret of their sense of smell?
If you’ve ever seen a dog, you know they like to sniff — the ground, people, each other’s butts. They like to smell just about everything. But why? We’re digging into the science of smell and how dogs are able to decode things we can’t even begin to imagine.
We also paid a visit to PawPADs, an organization that trains service dogs for people with physical disabilities, diabetes and autism.
Linda Ball introduced us to Breezy, who’s training to be a diabetes assistance dog. Here they are:
To train Breezy, Linda uses samples (pictured below) collected from people with diabetes. The person will breathe onto a piece of gauze when his or her blood sugar level is low and they put the gauze into a small tube. Then, Breezy is trained to recognize the scent of a person’s breath when his or her blood sugar level is low or high.
