A senior dog lost everything. Now he rides shotgun.

Ollie, a senior dog in Oklahoma, lost his owner and his home in the same day. Neighbors took turns caring for him until the Horse and Hound Rescue Foundation, a 50-acre ranch that rehabilitates Off-Track Thoroughbreds and shelters dozens of older and special-needs dogs, took him in for good. He settled fast. Ollie rides shotgun on errands around town and lobbies hard for drive-thru pup cups. He has also appointed himself the barn's official mouser, patrolling the feed room and keeping watch over the aisles. Nobody asked him to. He takes the job very seriously anyway. Senior dogs wait roughly four times longer than puppies in shelters, many arriving after an owner dies, through no fault of their own. Donations keep the bowls on the ranch full of soft food that lets the gray-muzzled residents stay active. "Ollie and all of his furry friends send a huge tail-wagging thank you for keeping their bowls full," his caregivers wrote.
