The Denver Dumb Friends League Holds Its 13th Annual Pet Parade At Elitch Gardens (PHOTOS)

On Saturday, the Denver Dumb Friends League held its 13th annual Pet Parade at Elitch Gardens.

Among the roller coaster splender and the temporary haunted houses that have set up residence at the amusement park, at least 45 pets threw on their best Halloween gear and strutted their stuff across the stage.

The pets competed in three categories: "Funniest," "Most Original" and "Best Pet/Owner Combination."

And it wasn't just for fun, the 45 pets and their respective owners raised a $1,000 for the Dumb Friends League, Denver metro's largest human society.
