In all honesty, I don't think a 4' fence is high enough. Instead of 1/3 of your yard made into a "dog play" area, how bout a proper kennel, with shelter?

If your not willing to modify safely containing this dog, how willing are you to modify your entire life for this dog? Doesn't sound like you really him, so why did you take him?

Nothing In Life Is Free. The concept is to make the dog work for anything he does and for every bit of food. Dogs like walks, make him WORK for it. You mentioned him pulling sometimes, so reward him when he's beside you.

Yes, there is a better way than the choke. Get a HEAD HALTI.
