We have a 57 lbs 5 month bullmastiff and she will not walk on a lead without pulling. I am following instructions on for walking her with a leash, and she will obey a little and for treats, but whenever she wants to, she takes off with us. She is uncontrollable in the woods. She is already too strong for my husband or I, and when in the woods, we have decided just to take the leash off, since she always stays within our sight and always comes to us for a treat. We felt it was better to give her the message that it is ok to run free, jump and run fast since we are away from danger. But even then we want to be able to recall her in case of emergency. She is expected to reach up to 115 lbs and very muscular.
But we want to teach her to be under our control for her own safety and our pleasure, particularly when we are walking on the road. We live in a very rural area and there are no dog parks or any park that even allows dog in the nearby towns.
Thanks for advice.
