I have two large dogs who have gone from being all about pleasing the humans, to being all bout who can beat the other one out of the door first. Personally, I think humans should get to go in or out of the door first, but they are so bent on winning the' first dog' title that as soon as there is a two inch crack in an open door they both peel though, and it usually involves pain and bare feet. They go deaf as soon as they get near the door. A set determination in their eyes. In or out, it doesn't seem to matter.( Except in going out there might be a squirrel. so the toenail punctures are a bit deeper.) Ideas?
