First off let me give you a little background before I as for help...This is not a pure bred GSD, so I'm not sure if this is the right place to post this thread. If it's in the wrong place, please accept my apology. This one is for Elle, the 2 yr old GSD mix...Most of our yard is fenced in and we normally do not have a problem with her leaving the yard when we let her out, but the last several days she keeps going beyond where she can and can't go. She has been fixed, so I know she's not looking for a male. We are working on getting that part fenced in, but it takes time and money to get it done. The problem is, if she goes into the next door neighbors yard, and they feel threatened by her, they have legal rights to kill her, and she really is no threat, but they're new neighbors, and I'm not sure how they feel about it. We do put her on a leash at night, so she can't go over there, but she does need to be free during the day so she can run and get exercize. What if any suggestions do any of you have to help me successfully train her to say in our yard, and not run over there?? Thanks everyone!!!
