Maggie is 14kgs so not carrying much weight and small for a BC. Winter is a quest for warm. When I visited my sister I discovered they all bedded their dogs under small doonas. I thought it was funny until this winter when Maggie was shivering so I succumbed. Now she is the picture of warm. I added the one of her on a walk just so you could see she doesn't sleep all the time. May yet have to buy her a coat. Her mother had never been inside a house, different for the offspring!
