Thanks for the advice, right now I do watch them %100 of the time. I just really want them to be able to play in the yard because they break all my crap in the house (3 lamps, 2 tables, computer, etc) and I want to set up a spring pole for them. As we all know no matter how much you walk your dog the second they are around their old friend its like they have been sitting around all day! I really really dont want to do an electric fence coupled with our current fence because if they did get over they would be shocked the whole time and I dont want them afraid of outside the fence. I just need to determine the height of fence/type that works best. I have never had a fence for them to jump before, my fosters I will ALWAYS watch, and my other pittie never jumped anything!
