Wow. I like me some dogs often enough but people can get loopy for dogs. Going for the huge ones is a tad weird IMO.
One of my clients got a Formosan Mountain dog, also referred to as the Taiwan dog from some local rescue group. A female, fixed, too bad because I really like this dog. Closer to wild dogs than most domesticated breeds it's not large but is tightly muscled. I love watching her run. Really sweet and smart also. Built like this one but light brown.
