My sister bought my mom a Jack Russell for her birthday three years ago. She got him from a place that rescues dogs from puppy mills- so he was a stud. My mom's name is Jill so she decided to call him Jack. The first several months we had him, Jack was not bad at all. Then, out of nowhere, for no reason at all, he started barking, chasing, and biting me and my boyfriend. My room is in the back of the house above the garage, kinda like a private "apartment" type thing. If we are in the living room in the front of the house, Jack will be normal, even let us pet him every once and a while. But as soon as we go down the step of the mudroom, he attacks. We have tried everything- saying "no no" or "bad boy", squirting him with a squirt gun (he just caught the water in his mouth like it was a game). When we had balloons for a birthday, he was scared of them, so I decided to carry that everytime I went downstairs. That lasted about a day, I realized i just couldn't carry around a balloon in my own house all the time. It's not only really annoying, but he has broken the skin on my boyfriend and my skin more than once. He wont go past the second step, so if I have anything but long pants on it's like a race to get to my room before he gets me. I'm so fed up with. What's up with Jack??
PS- I thought I should add that he is a bit spacey. We think it's from living in the puppy mill- but he is just completely out of it all the time.
PSS- This is only to me and my boyfriend. If someone else goes up the stairs to my room- he doesn't do it.
