as it is, he will sit if you stand still. he'll potty a couple times but then he'll sit ther and pant. so i take him to the street and walk back and forth in front of the house so that hell go in the tall grass across the street (he seems to like the tall grass for #2) but it takes a good 15-20 minutes. is there a way to encourage him to hurry up and gooooo!?
