nippy noodles!

Hey guys, excuse me the n00b dog owner, but what in the world is a kong?? Is it something you put treats in to keep them occupied tryin gto get them out or what??

My dog was never taught to roll over, it seems to come naturally to him. Tickle his chin and he gets excited and rolls straight over. Some get it easy :D

I was wondering about something related to this myself. I have recently aquired a 7-year-old dog, and I was wondering how to make him do his business in the same place, instead of all over the yard. Would it help if, like someone said, put some of his faeces in the place where i want him to relieve himself, and cleared up the rest?
