I had a dog at a very young age, which I can barely even remember, so I personally don't believe it's just based on having a dog as a child.
I believe anyone who wants to get involved is a dog lover. For someone who doesn't like dogs, obviously this program isn't for them. You have to have that bond with a dog, but the dog also has to have that bond and be able to trust you as well. It's a mutual give-and-take, sir.
