Dog Trap?

Guys, I'm not trying to be argumentative but y'all don't understand. I've been feeding this dog for 3 MONTHS and still can't get within a football field from him. He watches me from across my neighbors pasture when it's supper time, but won't come up until I'm gone. I've tried the trailer but I can't get a rope to work that is long enough to pull from inside the house and if he so much as hears my front door creak he is on the run again.

Terry, not planning on going anywhere with him. I'd like to have him if he will make a dog or even a good pet. He is gorgeous. Otherwise I'll cull him. Better than gettin splattered on the highway behind me.
