I don't have any pets currently, but I did house a cat once for my brother's girlfriend. The cat was not too much of a nuisance but sometimes it would sit on our hardware devices in the living room because it felt comfy there. Had a tough time convincing the cat to get off of our stuff, and I probably would say that with a dog, things would have been similar. Fortunately for me, no pets have ruined any of my hardware at all, especially my 360.
