The range of available pit bull statistics paints a very different picture of this much-vilified dog. Pit bulls are one of the most misunderstood of all dog breeds. These big-hearted dogs have a fearsome reputation when, really, they are one of the softer and more loving breeds.
I’ve never owned a pitbull myself, but some good friends of mine always had them; in my experience, they were gentle and well-behaved dogs. Very much part of the family, their pit bull terriers were gorgeous dogs.
The chance of being bitten is there with any dog. However, animal attacks often see pitbull-type dogs labeled as aggressive dogs. The truth is that smaller dogs are more involved in bite incidents than pit bulls. However, as these bites do not require medical treatment, they go unreported.
A study by the University of Pennsylvania discovered that 20% of Dachshunds had bitten a stranger. The majority of the six thousand people in the study claimed they believed their small dogs had problems with aggressive behavior.

Pit Bull Statistics
Pit Bulls Only Had 43% DNA Makeup from Their Pitbull Ancestors (Pitbull info)
Due to crossbreeding, most dogs are misidentified as pit bulls. With less than a 50% genetic match with true pit bulls, many modern pit bull-type dogs are a generic mixed breed.
Pit bulls remain one of the most commonly misidentified breeds. According to a survey, shelter staff visually labeled 52% of dogs as pit bull-type. However, DNA testing showed that only 21% were actually pit bull-type dogs. This difference shows that identifying breeds based only on appearance is often inaccurate and inconsistent.
There Are Around 18 million Pit Bull-type Dogs and their Mixes in the US (Pitbull info)
A recent study of over 200k vet visits found that dogs called ‘pit bulls’ are the most popular breed in at least 21 states and the most popular dogs in the U.S. overall. In addition, over 18 million pit bull mixes live in the United States, many of which are used as service dogs or for guard dog duties.

Approximately 1 Million Pit Bulls Are Euthanized Each Year (Oklahoma Animal Alliance)
Pitbull-type dogs account for approximately 40% of all dogs euthanized in shelters yearly. In addition, close to 1 million pit bulls are killed each year, as many people do not want to rehome these animals.
This means 2,800 pit bulls are euthanized daily, mainly due to misinformation surrounding the breed. 75% of municipal shelters euthanize pit bulls immediately upon intake, without them ever having a chance for adoption.
About one-fifth of Americans want a ban on Pitbulls (YouGov)
About 69% of Americans say they love dogs. But owning a dog also comes with responsibility, since any dog can potentially cause harm.
Around 23% of Americans support banning certain dog breeds. Among them, Pit Bulls are the breed most people want to ban. In fact, 88% of those who favor breed bans said they would ban Pit Bull–type terriers, which equals about 20% of the country’s adult population.
Due to being bred for bear and bull baiting and other aggressive pursuits, the pit bull is tarred with a brush that speaks more of breed ownership traits than dog characteristics.
Pit Bulls Ranked Lowest in All Categories According to a 2016 Survey (The Washington Post)
A small survey of 49 California college students saw pit bulls rank lowest in terms of friendliness, intelligence, and adaptability. However, along with the small niche test group, the results were based on images rather than any real dog interaction.

Pit Bulls Are Not a Great Threat to Humans (The National Canine Research Council)
While there is no denying that pit bull attacks happen, it is also a fact that all dogs bite. Unfortunately, Pitbull statistics are often overrepresented in the media.
In August 2007, there were four dog bite incidents involving different dogs in four days. One involved a pit bull; the others were other breeds.
The three attacks that did not involve a pit bull were covered by no more than one local paper. The pit bull bite was covered by 230 different national and international news agencies in some form.

Pitbull Adoption and Shelter Statistics
Pit Bulls Spend Three Times Longer in Shelters, Comparatively (The Washington Post)

Due to backyard breeding and a general love-hate relationship between American families and pitbull-type dogs, they often find their way back into the shelter system. As a result, more than a third of all dogs for adoption are pit bulls.
