Hi.. looking for a bit of advice/reassurance. I’ve a 3yr old collie/cocker spaniel cross who has always slept in the house.. this last few weeks once we take her outside last thing for a wee before bed she just goes into her kennel outside and refuses to come in..so she stays out all night.. she never barks or whines to get in and she seems quite happy. I’m just concerned with it turning colder.. is it ok to leave her or should I try harder to get her indoors? Usually during the day if she wants in she’ll jump up on the windowsill and bark but at night she just stays in her kennel from 11pm till DH gets up at 6 and doesn’t make a sound. She spends her evenings curled up in front of the fire so I’m baffled as to why she then heads off to a cold kennel outside!!
