Since Pits’ are considered dangerous then it’s surprising – at least to me – that there are so many of them. Could it be the owners got rid of them because they were afraid of the dogs??
No. What happens a lot is that people buy a Pitbull (whether because they know of their high quality and character, or because they want the toughest dog in the neighborhood for cool status) and then they find that they cannot get anyone to rent them an apartment or sell them insurance due to the unwarranted prejudice against the breed. Finally, they are forced with a choice of living in their car or getting rid of their Pitbull. If you have a Pitbull, you usually have to own your own home with a fenced in yard.
By the way, most people have zero understanding of the breed. I've owned them forever, and the ones I've owned and known do not have any more natural tendency to aggress against people than a Labrador Retriever. Unfortunately, this breed, due to the rep, is much more likely to be
aggressed against by people, i.e., a concerned father sees a pitbull, grabs his baseball bat from his trunk and proceeds to swing away in an attemt to frighten off the dog. Pitbulls, being fearless by nature, will usually not respond well to this.
Another problem is that when a Pitbull sets his mind to something, he doesn't stop till he accomplishes his task. In a person, we'd admire this quality, but in a Pitbull whether we admire it depends on what it is that he's doing. Pitbulls, like I said, are no more likely, by nature, to attack an old lady or child than is a Labrador Retriever (This kind of conduct, as with any breed, depends on early conditioning and socialization). The problem is that when a Pitbull decides to attack someone (anyone, old lady, child or lion), they don't quit till they are dead or their victim is dead, while a lab can be beaten off, or will just plain get tired of its attack and break it off himself. This is why a Pitbull owner needs to take extra precautions and needs to properly socialize his pet when it is young. Mine loves children, and pretty much anyone else, but he has been attacked by other dogs many times while minding his own business. Pitbulls, believe it or not, get attacked by other dogs more often than any other breed. This is because they generally don't have any fear of other dogs (more curious than anything else), and when another dog attempts to induce in a Pitbull a sign of subordination through intimidation, a Pitbull will likely act like he doesn't notice the other dogs dominant posture. This will cause the other dog, who is accustomed to inducing subordinate signals in dogs he meets, to attack - and then he's sorry he did.
The bottom line is that there is reason for caution if you own a Pitbull, but they are far from the monsters they are made out to be. By nature, they have characteristics that we'd admire in a human being, but those characteristics can be transformed by abusive upbringing and poor early socialization. Unfortunately, some people consider it fashionable to have a Pitbull, but then stick it on a heavy chain in the back yard, where it gets zero socialization, and then when it gets loose, it is a hazard to everyone it meets (just as you'd be if you were raised this way to adulthood). This, however, is not their nature as a breed. Raised as a member of the family, and properly socialized, there is much to love and admire in the breed.
