The range of disabilities that dogs can provide assistance with is so much more varied, and I'm the parent of a child with type 1 diabetes, which is, of course, classified as a disability, but it's not one that you can physically see. There are dogs that can detect significant changes in blood glucose levels, and I remember as a parent the number of sleepless nights worried about whether or not my child would go low in the middle of the night and I wouldn't know. The fact that we're able to have dogs that are able to detect significant changes like this is important. As we have an increase in the number of people who have mental health challenges, dogs are often used as companions to provide companionship and support in a way that's very definitely not visible.
