A sweet older pup is up for adoption on the West Coast after her guardian died. 

Bou Bou is up for adoption at the Muttville Senior Dog Rescue in San Francisco. 

She arrived at that location from a shelter partner following her guardian's death.

She is a 10-year-old female "all-American" mutt, notes her shelter — a combination of pitbull, dachshund and terrier breeds.

Bou Bou is also house-trained — and is living with a foster family she apparently loves dearly.
