In elementary school I read this book called “Flawed Dogs” and it was unforgettably wild. It’s about a dog who escapes some kinda confinement by jumping over a barbed wire fence and loses his back legs in the process, and then joins a dog gang and does dog gang activities. Also one of the dog gang members was a cat in disguise.
Honestly I should see if I can find a copy of it and reread it. It was pretty wild.

edit: I looked it up and maybe I have a lot of the details wrong but it’s still pretty wild
