UNION CITY, Calif. (KRON) — Alameda County firefighters were able to rescue a dog that chased a possum under a concrete slab Monday, according to a tweet from Alameda County Fire. The dog dug under the slab in pursuit of the possum, the tweet states.

Video of the incident shows a firefighter freeing the dog from under concrete while coaxing the animal out. The firefighters then handed the dog back to its owner who held it while its tail wagged.
