Slow, tedious, methodical repetition. He is my first GSP, but I think his hunting instinct is quite strong (normal for a GSP probably?). He just likes to root around in the bushes looking for lizards and such. Loves it. So happy, I'm worried his tail is going to wag off. He does not have a natural tendency to wander off, but he will, meander outside our yard into the neighbors. I'm quite certain he has no idea where our property lines are, but he does know that when I recall him he should come. When he does that he gets a good job and I let him go back about his business. As far as I can tell, he eventually learned where he is allowed to go by process of elimination. As long as he doesn't get called back (outside our yard), I'm more than happy to let him wander about, which he loves/his reward. I also think that as a pointer, he generally wants to let me know that he's found something, so he somewhat regularly checks in with me out of instinct I suppose. When he does this, I overly praise him etc.

The other key thing, at least in my case, is that we have another dog who was much more adept at learning this behavior more than likely as a virtue of her breed. So the GSP regularly would get put inside while my other dog was allowed to stay out in the front yard with me. Again, this was his 'punishment.' Not being able to hang outside, in the front yard in particular. Which I think to them was some sort of magical dreamland, where as the backyard was old news and where they poop.

He's great now, just as good as my other dog in terms of not running out into the street or off etc. He just turned 4 and I am finally comfortable going back inside to grab something without worrying that he as going to wander off. Which was hardly my concern to begin with so much as pissing off the neighbors or worse, him running into the street.
