My 8 month Pitbull gets way to jumpy and excited around my cousin and her dog... Whenever he sees her he starts barking and running around and jumps on and off her... He doesn't do this around anyone else.. Also whenever he sees her dog he gets really excited and pulls on the leash non-stop...

As I've posted, I recently got Jester out of a home where he didn't get much human socialization. He was on a chain as far as I know, all of his life. However, he is well potty trained, so that's questionable. I'm thinking it's because of this, but he's really skittish in certain situations...

I have a 3 yo mix (we think?)...her name is Sasha. She's a great dog, the only problem that we really have is that she barks every time somebody bumps the wall or touches the front door, at cars next to us in traffic, people (or sometimes no people at all) outside, the tags on our other dogs...
