She is just over a year old, and we got her on Christmas. As I've posted before, she has some behavioral problems and we've had a trainer here to help. I talk her out to do her business in the back yard. We have a small patch of woods in the back, behind our lawn. For the last week or so she pulls (really hard) towards the woods. She makes it extremely difficult on me as she attempts to dart across the lawn or into the woods. I plan to get a harness type leash, but when I say she's pulling, I mean pulling. This lab has pulled me into things and caused bruising as well. I notice she'll start to pull up the grass with her front paws after I don't let her get away. Almost like a digging, but in a frustrated way. She also refuses to come back inside, by doing a jerking motion over and over again as we approach the door. I had to physically carry a 70 lb lab inside my house today. I am out of money for trainers. I am out of will. I'm just getting angry now. Please help. My kids love this dog.
