A dog has died in America after a horse it was attacking fell on it and crushed it.

The pit bull terrier, which police believe to have been a stray, was chasing and biting the horse on Sunday (15 March) in Riverside, California.

The horse bolted and bucked off its rider. It was then hit by a 4×4 vehicle and fell on the dog, crushing it to death.

The horse suffered minor cuts and bruises.
