I had a beautiful Husky named Pal. I found him wandering the streets; one of the neighborhood kids said "his family moved away". He loved to run and occasionally escaped the yard. He would just run & run ending up a half a mile away. He also loved the snow. He would leap and run circles in the yard. Some breeds are just made that way. I do miss him. Huskies seldom bark, you know, they howl.
