Both my girls did as puppies especially at night - I always made sure what they wore as puppies fit really well if they slept in them so there was no way for it to tangle around their necks - but I'm up and down all night and a super light sleeper
but watch out if they wear them all day - tangles and knots !!! I now put CC Ice on Ice on them before dressing them - especially under their arms and back of necks - it really helps prevent that matting |
