This three-month-old puppy refused to leave his dead sister’s side after she was hit by a car.

The heartbroken dog stayed with his sister for two days until a kind-hearted person buried her.

Witnesses in Pixian county in southwest China’s Sichuan province said they saw two dogs, one grey and one brown, lying in the middle of the road.

Loss: This three-month-old puppy refused to leave his dead sister’s side for two days.

The heartbroken dog stayed by his sister’s side for two days until someone buried her.

Heartbreaking: Even when a grave was dug for the pup, his brother jumped into the hole too, refusing to leave.

The brown pup protected the gray pup’s body to prevent it from being hit by any passing cars, jumping up and barking if any got too close.

They remained in the same place for several days until a person moved them to a safe place on the side of the road.

Another member of the public then dug a hole to bury the grey dog.

Even then, his brother jumped into the hole too, refusing to leave his companion.

The brown dog was eventually picked up by staff at a local animal shelter, where he is being cared for.
