Im not sure why she does this but if its any help when Buddy was little i just had a vetbed in his crate not a bed the vetbed fits the length of the crate at first i would fold in half and have half the crate covered with a puppy pad after a couple of weeks i stopped putting the pad in and just had the vetbed Buddy never went in his crate as he wanted to keep it clean.Must admit i went down at about 5.30am the first couple of weeks then he seemed to wake later as the weeks went on and now its approx 6.45-7am.
