In Chicago, Tails in the City hosted its 8th annual Halloween Pet Parade.
They had over 250 dogs for a record breaking year and all the proceeds from the event went to PAWS Chicago.
All of the contestants looked great… especially the maid with her Puli dog as a mop. Ha!
A rep for the event said:
"Dogs lined up in front of Tails in the City pet boutique and paraded to Washington Square Park for a costume contest with prizes, refreshments courtesty of Downtown Dogs, and doggie agility courtesy of K9 University.
Everyone left with a goodie bag full of treats!"
Sounds like it was a great time for dogs and humans alike!
