Sigh. I'm not going to promote ignorance when it comes to dogs and specifically American Pit Bull Terriers (that's Pit by the way, not Pitt as in Brad) so I'm just starting a new thread for my comment. To say that any dog has a nasty tendency is just wrong and totally and completely missing the point of why dog attacks happen.

Yorkies have some of the same exact terrier qualities that these dogs have and they can often be aggressive. The difference is that their owners and others feel that's somehow "cute." Prey drive and intelligence can get many a breed into "trouble" and terriers are often more reactive than some other breeds. However, hunting breeds can also easily kill or course a smaller animal. Hardly ever does this prey drive turn into aggression towards human beings, they are normally two different things. But somehow people see them as logical stepping stones when they are not.

There are hundreds of dog attacks in the US every day. Some are fatal. The only ones that get reported in the news are the ones that involve larger dogs or, specifically, Pit Bull Terriers.

They aren't "nasty" or "dangerous." NO dog, regardless of its breed, is inherently so. When a dog is properly socialized and raised in a non-aggressive and positive enforcement environment, there's a very low incidence of aggression towards human beings and things like prey drive are usually relatively easily controlled so that they aren't dangerous towards smaller animals.

People who backyard breed, raise dogs for protection and train them to be aggressive (either on purpose or passively through neglect and abuse) are "nasty" and "dangerous."
