That would help alot in a plane. ;)
He doesn't crap in the house. He has thrown up twice, by the door, in almost four years. But, he started his residence in a wire "box". I brought him home from the "Humane Society" kill shelter, a couple days before the sentence was to be executed. I had just stopped by, perchance, and the result has become my fast friend, and companion. I think dogs are God's gift here on earth.
By putting him into a cage during the times I was away, he learned to hold his "stuff". Dogs, by nature, don't crap close to their beds. They are also eager to please you in every way. That's why you see pictures of dogs, beaten and battered, licking the one who perpetrated the deed. Dogs are trained and led. If the "master" is not a leader, they want to lead him. Michelle makes the news when she took the dog out on a leash.
The Zero's has no clue about dogs. Too many people are just like them. Ignorance can be cured. He is not ignorant. He is arrogant, and wanted another photo op. Note a handler for Bo, but GWB held Barney as they walked off the plane, and Barney ran after them on the south Lawn when George put him down! Good dog.
