[Crackers]

I'd love one of Fourthwall! He's a very large canine with retractable claws that often poke out and are very cat-like. His build solid like a fighter but isn't overly broad/bulky, maintaining a sleek enough build to climb trees and hold a very feline-like agility and grace despite his obvious strength. He's also covered in random scars, has deep red eyes, and has a coat that is mainly black with various brindle patches of gold. The gold brindle has no symmetry or patterns to it and appears random. I don't really have an examples right now so you can just be creative with it
