10. Boxer
Boxers are a short-haired, medium-to-large breed from Germany. Their physique does not reflect their personality. They are easy to train, calm, and intelligent. These energetic and devoted dogs are good with kids and other dogs. Allboxerinfo.com describes them as strong hunters with powerful jaws. Their broad muzzle and open nostrils help them breathe while holding prey. Without proper training, they may attack small animals aggressively.
