why the heck does my dog (a) continually try and go downstairs when I'm not looking (like when I'm vacuuming the basement cat's room), and (b) chew up the upholstry attachment of my vacuum that fell off on the bottom of the stiars when I just bought him a bacon flavored chew toy?

rrrrr, it makes me mad enough to want to shake him. so he's now in his crate and I think we're going back to being on the leash around the house again.
