They are not all cases of mistaken identity. Pit bulls do often actually maul people... and they don't look a thing like a Greater Swiss Mountain dog.
You may delude others with pictures of rare breeds that look a little like a pit but are rarely seen roaming the streets, but you don't delude me. I know a pit when I see one, and I don't think all these street punks are keeping "Cadebo" dogs and "Dogo Argentinos" nor any of the other rare pit-type dogs that are set up there as 'gotcha' answers...
Many of pit bulls are loose cannons. You admit that, but not the damage they do...
I never said that pit bulls are loose cannons and I never said that these dogs have not mauled anyone. What I did say is, pit bulls are not human aggressive by nature but through subpar standards and improper breeding there are many variations of the breed. These are a very poor representations of the breed. However, they do exist. A properly bred and raised dog will never attack a person.
I am not here to "delude" as you say but to discuss this matter in a civil manner. Many of the dogs on that site are popular and can be seen on the streets. Dogos, Presa Canerios, Alapaha Blue Bloods, and Cane Corsos, for example, are very popular.
Also, you mention that Swiss Mountain dogs do not look anything like a pit bull. My dog is tri-color. He shares the exact same markings as a Swiss Mountain dog and was actually confused for one the other day at the park.
Once again, I will say that properly bred and raised pit bulls are not "loose cannons". Any pit bull that does attack a person is a poor representation of the breed. The dogs are not responsible, the owners are. The same goes with any other dog.
