We watch both of ours when they are outside to ensure we know they have emptied their tanks. Does yours not empty himself outside when he goes (a little here, a little there, etc) or is he too busy outside with other things to empty his tanks and you thought he did?
Ours are running to the door to go out (they don't wait long at the door) but ours still go inside sometimes, typically because we are not watching them closely enough. My wife had to clean up smeared poop on the tile floor in the mudroom earlier this week. A ram lamb got out of the barnyard and she thought putting him back would take very little time; so she left Grant and Lee loose. The chore took longer than expected and by the time she got back they had pooped and then stepped in it spreading it around the floor.
Lee has decided that "catch me if you can" is a fun game to play (I don't play it); now he drags a long line every time he goes outside. This has changed his attitude about coming since we can enforce it. Without the line he would look at us when we called (even while offering a treat) and then run the other way.
