For the past 10 years, about a million pitbull-type dogs are surrendered each year to shelters. This is the No. 1 breed surrendered to shelters, and rescuers are desperate to re-home these animals. Many have a label: "should be the only pet" or "dog should be placed in childless home." This seems to imply it is dangerous toward other animals or kids.
Pitbulls are one of the most powerful dog breeds with a strong gameness trait (not to quit), making pit attacks the stuff of horror stories. Pitbull types bite down, clamp and shake, causing severe tissue damage. Oftentimes, bystanders are powerless to stop a pitbull attack.
Some people argue that dogfighters have removed the human-aggressive trait in pitbulls from the gene pool by culling. This is a myth. Many pits come primarily from backyards of those trying to breed aggression, not good temperaments. Often, their dogs are the product of reject pits purchased from dog fighters as cheap stock.
Of all the dog breeds, they are the all-time No. 1 killer of humans and other people's beloved pets. In 2013, thousands of beloved pets were killed by pit-type dogs. Between 2004-2014, 208 people have been killed by pit-bulls in the U.S., according to dog bite fatality statistical data collected and recorded by DogsBite.org.
