border collies love to run u cant help that but u can stop the fact that she always runs away U could take her to obediance classes or U can reteach her come and reward her when she stays in the yard. My dog also loves to run away and I give her a treat when she stays in the yard. and when she trys playing game i just say Woah which means stop and stay where u r then i go up close to her and say Come and she comes see what works for u
good luck
