Simply put, any breed of dog can bite, and any breed of dog can make a perfect family pet. Yes, the bigger and stronger the dog, the more damage it is capable of inflicting, although I have seen horrific footage of bite wounds from small dogs such as Jack Russell Terriers and Chihuahuas as well. Which breed of dog was named ‘most aggressive’ in recent scientific studies? The family Dachshund. Does that mean we should add Dachshunds to the list of ‘Dangerous Dogs’ as defined by lawmakers in favor of BSL? Of course not. Years ago it was German Shepherds in the bullseye. Then Rottweilers. Now Pit Bulls. I’ve trained countless Pit Bulls, and have found them to be among the most loyal, smart and trainable dogs I’ve worked with.
