That blue blackground is ok
Its really not a myth that pits and many terriers in general(think Kerry Blues and some of the others) are just not that good with other dogs. Its not a negative, it just is what it is. Some pitties are fine and others just really are not.
They were bred to be dog aggressive. Heck, terriers are *scrappy*. Doesn't mean they are bad dogs, just not good with each other.
I had a pit mix and she was very dog aggressive. We had other dogs, but, she had a tendancy to go after them occasionally. I broke up more than one fight. Though, that is just sometimes a dog.
