I am hoping someone can remember the title to this movie, it was about a group of kids at winter time that built two snow forts and had a war with each other. The main characters were a boy and a girl. I was thinking that dog was in the title somewhere. I remember this movie and wanted to see if I could find a copy of it and hopefully someone can tell me the title.

"Snow Day" or "Snow Dogs"?? Hope I helped.

Sounds like The Dog Who Stopped the War
