What is dog who stopped the war?

The dog who stopped the war, also known as La Guerre des tuques in French (The War of the Tuques), is a Canadian film released in 1984. The movie was directed by André Melançon and was based on the French novel La guerre des tuques by Roger Cantin.

The story revolves around a group of children who engage in a snowball fight during their winter break from school. The game of snowball fight gradually escalates into a full-blown war, with each team building snow forts and devising strategies to outdo the other. The main character, a dog named Cleo, plays a crucial role in bringing the fighting to an end.

Cleo is a stray dog who had been watching the children play from the sidelines. She eventually starts to play with them and ends up getting caught in the middle of the snowball fight. However, when one of the children gets injured, Cleo's compassionate nature leads her to intervene and stop the fighting.

The movie is known for its themes of friendship, conflict resolution, and anti-war sentiments. It has since become a classic in Canadian cinema and has been remade a few times in both French and English.
