Funny stuff.....I would write to the company and ask!
Their website says they use real snowflakes :
Fruitables Snowflakes A true first of its kind – Fruitables deliciously festive dog treats made with real snowflakes make the perfect Holiday stocking stuffer or party gift for your little four legged family member and friends. Each Fruitables Vanilla Snowflake package includes 300 perfectly unique snowflakes sustainably harvested from the mountains in Crested Butte, Colorado and then combined in a pumpkin granola & yogurt combination that smells and tastes like 9 Calories from heaven.
