We had a scary incident with a pit bull a few months ago so I'm not too fond of them right now. A male pit for whatever reason decided to attack my dog while we were out on a walk. The pit was tied up in his yard and decided to charge straight at Bear for whatever reason. The pit easily broke through his chain and went straight for Bear's head. Bear at first tried to defend himself, then he tried to get away. The pit locked his jaw on Bear's shoulder. With the pit attached to his shoulder, Bear couldn't do much and we we're able to move in, calm Bear down, and wait while the owners (who had heard the fighting and came out of their house) tried to get their pit to let go of my dog. It took a while. Fortunately Bear has really thick, loose skin on his neck and shoulders and walked away with just patches of missing fur and a few minor scrapes around his ear. He was very sore and bruised for a couple weeks afterward, but was ok. My other dog Meg was there too, though not involved. She was dog reactive on leash to begin with and got worse after the pit attack.
No one breed is bad, but pit bulls are powerful dogs that can do a lot of damage if they want to. Prior to this incident, I liked them just as well as any other dog, but now unfortunately that one attack is what I think of every time I see a pit bull (which isn't too often in my neighborhood). I need to meet some sweet well-behaved ones.
