Kind dogs are the best dogs. They're the ones who get along with everybody, who give out giant grins freely, and who never treat a newcomer like an outsider. These dogs are made with nothing but love and fur, and it shows fully. And what's even better is the fact that you can use that trait for even more good. Since your dog is so kind, there are a bunch of activities to choose from that would compliment that kindness so well. Things you could both do to help people in need, loved ones having a hard time, or even strangers having an off day.
As you can see, there is plenty of kindness to be spread around by an amicable dog. A dog who is gentle is good with kids, strangers, and pretty much everyone else too, so there's a lot you could both do to play super heroes. Only, you know, more realistic ones. And no, this is not an excuse to wear costumes or capes. Just be yourselves and spread the kindness and good will around!
