San Francisco's Muttville Senior Dog Rescue recognized the special day with its first in-person adoption after 19 months.
Seventy dogs age 7 or older were at the center on Alabama Street were looking for their fur-ever homes.
Muttville recently rescued its 9,000th senior dog, a stray pup named Peabody from Fresno.
If you're not able to adopt a pup, you can volunteer at Muttville or donate things like food, toys and medicine.
The rescue says it's looking for volunteers to play with dogs and take them for walks.
