Hello, I'm new to the forum and hoping to get some advice. My 3 yr old spayed boxer has all of a sudden started either jumping the fence or busting out the screen door (if the big door is open) when other dogs are walking down our street. We have lived in our house for over a year, so not new surroundings. The screen door issue was fixed just by making sure the big door is never left open. But, now that she is jumping the fence I don't know what to do. We have two dogs that live beside us that she loves to play with and has never acted aggressive toward them. We also have a male bichipoo that she gets along fine with. But, twice now, she has jumped the fence to run across the street and be very aggressive to two different dogs being walked. She didnt hurt either of them, but I'm afraid she will. The man walking the dog today was very upset (understandably) and threatened to call the police. Any thoughts/suggestions?
