If you've got a killer costume for your dog or just want to ogle and pet other people's dogs, you'll want to be at Denver Beer Co., 1695 Platte St. They're having a dog costume contest from 5 to 8 p.m.
The categories are best solo pup costume, best human-pup costume and best pup-pup costume. Prizes are $25 gift cards.
Of course, they'll be serving pumpkin beer and treats for humans and doggos.
