our pup seems ok with her pen at the mo, she won't need it forever mind; though she's in it now (took herself to bed, so proud

) and has slept through the night every night except her first night; and always uses her mats (well except for the odd little wee on the rug after a play, but we were expecting a lot worse!). we do spend a lot of time with her, and thankfuly she seems to be settling in. we're playing it by ear, at the minute she's happy running in and out of it, but when she gets more settled in i doubt we'll need to use it.
