Snowflake was a Butterfly Puppy, a breed that was specifically bred for noble ladies of Tortall. She was owned by Lewyth of Disart, a young noblewoman who was lady in waiting to Aeldra of Queensgrace.
Snowflake first met Achoo, Beka Cooper's scent hound after she had escaped from being beribboned by her noble mistress. Achoo cornered her and sniffed her, but Snowflake soon warmed to the bigger dog and they became friends. This made Lewyth like Achoo and become friends with Beka.
