This winter we have been experiencing extremely cold weather with daytime temperatures around -31 degrees Celsius. Night time is even colder if you can believe it and this is not even mentioning the wind chill. My son's two year old dog Leto, is a mutt but she looks sort of like a grey hound or a whippet. She is young so she is able to run a lot to stay warm but this year we decided she needed extra help staying warm. We decided on this beautiful red sweater for her and as soon as she put it on we could see that she was warmer in just the way she didn't shiver when she walked. We will probably by another coat next year just to help her out and to make her look all fancy like many of the other dogs in the dog park. It is a perfect fit for her and worth every penny.
