No snow here in Alabama, but it is cold, going down to 8 tonight, and Blithe seems to love the cold weather. Due to physical limitations, I'm unable to walk him, so I have a dog door and both of us love it.
The dog door is inset in the bottom of a low window, and Blithe will stand with hind legs on the inside window sill and front legs on the outer one, surveying his kindom outside. Unfortunately lots of cold air comes in when he does this, and also the seal on the door is no longer very good as it's so old. I've found they no longer make this size door so I can't get a replacement flap. Nevertheless, he is in and out all day when it's cold and seems a lot more frisky, and can come and go when he pleases.
