Pit bulls are the media's current "target" dog. Here's the thing about those articles- if a dog looks like a pit bull with no proof of it's breed, it's labeled a pit. If it looks like it COULD POSSIBLY be PART pit bull, it's labeled a pit. If it's a dog of unknown breeding, it's often labeled a pit. If you do more research into it you'll find that this is the case in so many of these sensationalized "reports"- they are meant to generate web traffic and sell newspapers. And they do!
ANY dog that's unsocialized as a puppy can/will attack another dog or person. Pit bulls are simply very strong, slightly bigger dogs that can do more damage than a small dog. While it is true that they can have strong prey drive, but it really depends on the individual dog- and if it's an issue, it can be fixed with plenty of socialization early on.
I have had pit bulls all of my life, and have never, ever had problems with dog aggression- because we took the time and effort to properly socialize them as pups!
My pit bulls live in harmony with my boston terrier/frenchie mix and my yorkie, they are all very bonded!
I'm sorry if I'm coming off as 'preachy,' I don't mean to! I just want to share some information with you guys. Pit bulls get a very undeserved bad rap. They are the original "nanny dog."
That being said, I'm really sorry to hear about the troubles you're having with Lil Bit. I def agree with getting him a physical exam at the vets and then maybe find an experienced dog trainer that can help. Good luck!!!!
