I live out in the country and i dont keep my boxer inside, she has a lot more room outside in my yard which has a chain link fence around it. So i had a lot built just for her so that of the night and while the kids are playing we can put her up. the lot is 40 ft x 10 ft. My problem is that when i put her up today she was climbing out the so i put some fence over the top of it, so i went 4 wheeling with my brother in law and when i came home there she was out in the yard. I cant seem to find anyway to keep her up i bought a nylon rope made a runner for her and put a collar on her well i came in, i didnt watch her for a minute and what do u know she was out. im afraid to put the collar on to tight, how do i know when it its to tight, and does anyone know any ways to keep her up i have fit with her all day. Any advice on either way would really be appreciated. Also i have got it fixed so that she cant get out of the top and now she gets out the bottom and when i put the runner on she jerks the collar off and comes on under the fence.
