13 week-old Jasper now has a firm grasp of sit and down (will usually go straight into down now since when we are inside I am asking for a down to not chase the cats). I am trying to allow more "house time" while he is on a leash and having fantasies that he will be able to settle down on a mat or in a crate (door open) and just relax. Right now he wanders around sniffing crazily and constantly goes into "down" if I look at him b/c he wants a treat. I have been trying to teach "stay" but so far, have not been successful. Any tips for teaching settle and stay?
