The lady who was quoted saying that was herself mauled by a pit bull in California, and she is the founder of dogsbite.org.

To compare a game of tug-of-war to breed specific attack behavior is a bit of a leap. So I would suggest looking at the readily available numbers instead.

Just this May, dogs.petbreeds.com posted a well-known recent study, notable for it's methodology and it's scale covering 32 years. Petbreeds re-published this report as they, "concluded that this report gave a sufficiently thoughtful and unbiased summary of dog attacks in the United States." And they included the reports specific methodology.

"Dog attack deaths and maimings, U.S. & Canada (1982-2014),” compiled by ANIMALS 24-7 is a 32 year study from readily available records that focused on the number of attacks doing bodily harm in the past 32 years, which includes fatalities, maimings (loss of limb or disfigurement) and other severe injuries that required hospital treatment. The study is easily Googled.

No.1 In Attacks doing bodily harm: 3,397, and deaths: 295 is the pit bull. The astounding thing about that compilation study is that not only did pit bulls account for the majority of deaths and injuries over all other breeds by a wide margin, the margin is so shockingly wide that pit bulls accounted for deaths and injuries over the next nine breeds in the top-ten list COMBINED, and even then by a great margin.

For example, even though considered vastly outnumbered by German Shepherds who are the second most popular dog breed in America, for deaths and attacks causing bodily injury, the Pit Bull has been involved in 2,000% more deaths and 3,000% more attacks causing bodily injury than the GS.

If those public records and their compilation are accurate, it's hard to see how it is breed bashing.
