Dozens of spooky, eccentric little creatures haunted the streets of downtown Denver on Sunday.

From superhero canines to sinister pups, some 75 dogs and other pets participated in Denver Union Station’s “Howl-o-ween” parade, according to organizers.

“We just love to bring together people around animals, around their pets, for it to really be community focused and a feel good Halloween event,” said Sigri Strand, director of marketing at Denver Union Station and the Howl-o-ween organizer.

“It’s just a good chance for everybody to get together,” she said. “Pets always make us happy and remind us how much we have in common.”

The event partners included Red Fern Animal Rescue, a Denver-based nonprofit.

Howl-o-ween, Strand said, is “a good chance for people to remember that animals, you know, they need our support, too, and they’re often our biggest champions.”

This year’s event preceded Halloween, which falls on Friday.

Organizers said the parade is just one part of the approach Denver Union Station has prided itself on — bringing people together for events, and not just serving as the city’s central transportation hub.

On Saturday, hundreds of people celebrated there for the Denver Nuggets’ home opener.

“We like to say that we’re connecting cultures here at Denver Union Station,” Strand said. “We’re connecting the whole city to the entire world.”

“All of our events are really geared towards bringing the community together,” she added.
