Bella is a little over 4 months old. I got her when she was 9 weeks old.. I have been trying to take her on a walk to help release energy but she will only walk around yard and around the driveway that goes around our house. If a dog barks no matter the size she starts running towards the door. If I even try to leave the yard she pulls in the opposite direction(back towards the house) Even tried a retractable leash she runs around until I start getting her to leave the yard she just won't she is not happy unless she is in our yard. I want to start walking to lose weight but I want to be able to take Bella with me but I can't get her to leave the yard.
