I have a Treeing Walker Hound/ Beagle mix that I rescued from my local shelter. She is about a year and a half old. When I first brought her home she was keen to walk with me, but she would pull so hard she'd almost drag me. I thought I had it under control until something new happened. Now, not only will she pull me even if I correct her, she has started refusing to walk if we're not walking in the direction she wants to go or if we turn toward home. So it's a battle. Some times she'll walk fantastic, it's like she is focused on getting the exercise. But almost half the time she'll pull, pull, pull, and then stop in her tracks and lay down, or sit and refuse to move. I've tried longer walks, running, treats, and trying to redirect her focus. What can I do? What suggestions do you guys have to help save the walk. I'm frustrated and are seriously considering professional help. I can't give up on her, I love her to much to throw her back to the shelter. HELP!
