Yodel and Sniff are characters from Disney's 2002 movie, Snow Dogs.
Role in the film
Yodel and Sniff are first seen along with Mack, Diesel, Scooper, Duchess, and their leader Demon except Nana attacking Ted Brooks, the son of their late mistress, Lucy Watkins, whom he never knew, in their home cabin. In the morning, they are all heard and seen barking for no reason until they are silenced by Thunder Jack, Lucy's husband and Ted's biological father whom he doesn't know yet. They're the wheel dogs of the sled team. They follow whatever Demon tells them to, including running off without a musher to guide them.
