So my neighbors dog was outside at night, and I went to go to my car and he started barking at me, well I go back inside. I assumed that they would have caught him before morning. The next day in the morning I take my boxer, Zeus to go potty, so I let him out. I then hear barking and the neighbors dog is chasing mine up along the fence (the fence is separating them). They are both barking at each other. I have no shoes on so I run and grab them, to bring my dog in from the backyard. Well, while I was grabbing my shoes, Zeus jumped the fence. I go out front and it seems like they are playing or just starting to fight. Then, they start biting each other. I run out their not thinking, so I can pull my dog away and get him inside. They are fighting on my lawn and the neighbors lawn. The neighbor finally comes out and grabs his dog, and Zeus runs to the front door he is bleeding a bit, and has puncture wounds. I call vets everywhere and they are either booked or closed, so I have to wait until Monday to take him in. Zeus was in pain a little yesterday and then today he is okay. I am going to take him in anyways to make sure there is nothing wrong. I grabbed a long leash and a stake so when my dog goes outside he wont jump the fence or get out, when the neighbors dog is loose. My dog is a lover not a fighter, my dog has been around many dogs from small to big, and plays well with them. This has happened before where his dog was out and I didn't know he was out, and I took my dog to go outside, then they are barking at each other, but they didn't get into a fight.I dont know if I should talk to my neighbors and see if his dog got hurt? Their's and my dog look a lot alike except he is a pitbull or a mix between. Yeah but anyways we are both at fault, my dog jumped the fence while their dog started the fight or provoked it.
