JohnBlair my advice is fence an area off in your back yard for your kids, you don't have to fence your whole yard imo. Its an improvement to your property that adds value. And yes I'm a believer that most pit bulls get a bad rap, if they are loveingly raised they return that love a 1000 times imo.
Are you serious? I must live on another planet. When my kids cant play in my backyard because you cant keep your dogs out of my yard, you pay to build the fence in your yard to keep your dogs in, i don't have to pay to build one to keep them out.
John, you've already asked the lady to keep the dogs out of your yard. Now, you have to tell her and then call the authorities. Don't feel bad about being a dick because if she was a responsible pet owner, this wouldn't even be an issue. Once you have it documented that you've called on them once or twice, no one will say shit when you give them the "hole in the head" disease in your yard and call to have them picked up. You've already put up with way more than I would at this point. Good dog, bad dog, bad reputation, or unfair judgement of the breed isn't the issue, violating the personal property and space of your family is the problem.
