“The six breeds or types of dogs most commonly identified as high risk for aggression are the Akita, Chow Chow, Doberman Pinscher, Pit Bull (usually includes Staffordshire Bull Terriers, American Pit Bull Terriers, and American Staffordshire Terriers), Rottweiler, and Wolf-hybrids.
Most animal control ordinances define a dog as “vicious” when the dog, without provocation, has bitten a human being or killed or maimed a domestic animal or if the dog is believed to be of a breed that has a high probability of such aggression. In addition, some breeds, namely Pit Bulls, may qualify as “vicious dogs” simply by reputation, not because a specific dog has behaved in a harmful manner.”
Note: the tendency of a higher percentage of their owners’ personalities towards risky behaviors is noted:
Note: The only time I’ve been bitten by a dog was by a childhood friend’s Chow Chow. He and I were sitting on the floor playing Monopoly and the dog suddenly attacked me.
My sister was recently attacked without cause by their part Pit Bull. She simply stood up to get a glass of ice tea when it attacked without cause. Only her grown son’s quick intervention minimized the damage. The dog was put down.
Both of these dogs had never shown any signs of aggression prior to these attacks. Neither set of owners were inclined towards risky behaviors and were responsible and knowledgeable pet owners. This shows how unpredictable vicious breeds can be.
I have, however, over the years witnessed a series of dog owners carelessly putting their Pit Bulls into public situations where it was quite ill advised. And each of these owners’ body language clearly indicated that they dared anyone to say anything.
