Dogs will follow you to the end of the earth if it means proving their love. But you know what’s a better loyalty test? Dressing them up as a goofy jack-o’-lantern or, god forbid, sexy four-legged nurse, and seeing if they don’t give you a little side-eye.

On Oct. 26, owners can test the limits of their pets’ patience at San Ramon’s free “Howl-O-Ween Costumed Pet Parade.” Taking place at the City Center Bishop Ranch, the event invites both pets and their owners to don outfits and strut their stuff for the amusement of the general public. People are invited to preserve the memory at a Halloween-themed selfie station. And from 1-5 p.m., nearby “dog gym” The Hub is putting out a miniature obstacle course and a ball-pit sniff patch for hounds. For a $10 entry, the gym is also hosting special “haunted obstacle adventures,” pro-pet photography and trick-or-treat training (ends at 5 p.m.; limit one dog per owner).

This isn’t the only action happening at Bishop Ranch that day. There’s also a Beer City Half Marathon, 10k and 5k starting early in the morning followed by a Beer City Festival centered around Fieldwork Brewing. Expect appearances from local brewers, live music, games and food – plus lots of funnily dressed dogs kicking back after their big show.

Details: Parade begins at 2 p.m. in Alexander Square at 6000 Bollinger Canyon Road, San Ramon; free, citycenterbishopranch.com/events/howl-o-ween. Details on the Beer City races and festival at beercitybishopranch.com
