Thank you everyone.
She used to be willing to wear a harness and go for walks safely in the woods but in the last year she started refusing to put it on ( and if she refuses you really can't make her). So for a while she was not getting time outside because we couldn't do it safely. Finally she was so unhappy I started letting her out in our fenced back yard. She usually just played for a few hours and came home . She never climbed the fence. For some reason this time she did. I feel terrible.
