Police: Puppies found dead in dog food bag

An Oklahoma animal rights organization is offering a reward to anyone who has information about the death of four dogs found stuffed in a dog food bag.

The puppies, who suffered head injuries, were found dead Tuesday along the side of a road. The bodies had been stuffed in a dog food bag.

Police said they were flagged down Tuesday morning after people driving by saw the animals.

The photos from the scene are gaining attention on social media.

The Oklahoma Alliance for Animals is offering a $5,000 reward for information leading to the arrest of whoever killed the dogs.
