Hmmm.....ya, not much thinking needed on this one. DEFINITE FOE!!! I mean seriously......what kind of crazy person thought this one up?!? Saturday we're over at M-Guy's friends' house and I get to play with their female Pit and big male Rottie. It was a pretty sweet set up. There was a big opening in the family room to lead out onto the deck, which then went down to the yard with stairs you barely had to use if you didn't want to. Of course I chose not to. We got to play chase a bunch of times and could bring toys and stuff in and out of the house. I got the other two dogs riled up and into a good wrestling match, and of course being the good dog that I am thought we should take this rough housing outside to appease the humans. I spring free from the other two to have them chase me outside when WHAM!!! This invisible force later described as the "sliding glass door" was put in place so the humans could turn on the "air conditioning". This sliding glass door thing is just wrong. I'm all for running into things, walls included, but there's a technique to it. Full speed, face first because you can't see it coming is not it. The only thing I haven't figure out is who is more insane - the person who invented this messed up object or the people crazy enough to buy them and put them in their houses.
