He is strong and muscular and now about 90 pounds. My wife has a gentle leader and with that she can handle him on a leash.  I can walk him without a leash and he behaves like a gentle dog -  if someone comes in the driveway up to the house and he's loose  all it takes is a command "its ok Trigger" and the stops and sits down.  When we go to work, he stays in a 300 ft fenced enclosure and has a dog door to get into a heated garage in winter and also out of the sun and heat in the summer.  He very well behaved all the time.  and a wonderful pet. And his favorite thing is riding in the pickup, and his second favorite thing is sleeping on the bed so long as he can be touching one of us.
