should that be "splatter zone" maybe Anita??
I have to say that when we got Millie we didnt have a crate at first, instead we bought a hard plastic basket - this was placed in the kitchen diner (we also have laminate). Then at night she came upstairs in her basket with us to bed.
Through many trials and tribulations we have been with Millie's sleeping arrangements!! but in the end we bought a crate for her to sleep in at night in our room - and thats where it stays, with her basket downstairs in the kitchen for during the day.
I would say the dining is the best bet - your puppy won't be in there all day anyway, only when either you or she need a time out, when you're going out or at night. So I wouldn't worry about the pup being on its own, cos ideally when you put it in there, you want it to be on its own anyway .. if that makes sense??
