Hi, I have a 17 month old black lab who is getting worse at chasing wildlife, especially deer. He's my third lab and I've tried all the training methods I can think of including a long line, but he's getting worse. He's started taking 10 minutes to come back now and I'm very worried that he's going to get himself hurt, or worse. I'm really at a loss as to what to do - can anyone help please?
