Are there THAT many bad/abusive owners of pitbulls vs. other dogs?
Sort answer..... YES!!!!
Think of it this way.... You're poor, want a big dog. Unfortunately, people who breed Sheperds usually look at the homes they are going to, BUT people who breed pits USUALLY could care less. Reason? Sheperds are more expensive to care for, and are generally a higher class dog than a pit. BUT a pit can be just as nice as a Sheperd, just depends on the owner as stated in my above post.
The unfortunate truth is, people that don't have much money and are a-holes but want big dogs go for pitbulls. I'm not saying all pitbull owners are poor, just the majority of the attacking dogs are owned by poorer folk.
