Unfortunately we live in a remote area and trainers are few and far between. I took him when he was younger but she was 45 minute drive each way. And now, she is recovering from a broken leg herself.
I do have a muzzle and we are working with him to take treats from it now.
We live on a 30 acre farm and have 3 acres fenced with InvisibleFence. None of our dogs are ever tied up, except this one in particular, for short periods of time when we are not in earshot of him. (Taking a shower for example.) We do not leave them tied up alone either. The times he has chased a person, someone has been home/outside with him. If we leave, we usually lock him in the house or take him with us.
