We all know that dogs are man's best friend, but a Black Labrador proved to be the best friend of a Yellow Lab after it had been struck and killed in traffic.
The Black Lab never left the side of her canine friend after being struck by the car.
Video shot by a passerby has been circulating the internet since it first was shared on Saturday.
According to a KTLA.com report, the two-year-old Black Lab, later named 'Grace' by caretakers at a local animal shelter, did not have tags to identify her owner.
The KTLA.com report says that 'Grace' was adopted by a Good Samaritan who helped out the two dogs the day the video was shot.
