My new boxer puppy "Ali" doesnt like her leash. She loves to run around without it outside but we all know that isnt safe. I dont especially since I had my another boxer run away *she was abused before me.. didnt know what love was I guess* When shes on it she usually doesnt move and just sits. Shes 12 weeks old.. Any way to get her to like it or will she just "grow into" it? Thanks
