I honestly like smaller dogs as well, I like for them to stay under a 100 pounds. In my humble opinion I think 80-90 is the best weight for a dog, big enough to stop with brute force but small enough to conserve energy. The Dogo Canario I fostered was about 120 and I felt like the dog was just too big. I am also not a big guy lol so maybe that;s why I prefer them under 100 pounds.
