I adopted a gorgeous 1 yr old boxer / pit mix recently. She is great indoors, house trained and mellow. Whoever owned before must have kept her in a box because she is a different dog outside. Everything stimulates her. She pulls on her leash and her walks are feeling like a chore. Additionally she cries when I leave my home. I feel trapped and regret her adoption. People are telling me things will change with obedience training, but right now I feel overwhelmed, my anxiety is sky high and I am struggling.
