I tried to do this with Nebo as a pup, but I kind of slacked on it so it didn't really work. He still tends to go in the same general area...problem is, there's more then on general area he prefers. When he's in the dog run he does always go in one spot though.

Wow, a GSMD?? I LOVE swiss dogs, and those are absolutely gorgeous! I've only met one irl......he was huge, and a total sweetheart! I'd imagine they would be pretty hard to find?
