Shocking footage has been uploaded online showing a giant alligator calmly swimming through the water with someone's pet dog hanging lifeless in its jaws.
The pup appears to be a black Labrador wearing a bright red collar.
The location where the video was recorded is not certain, but it is thought to have been filmed in the southeastern USA, an area plagued by gator attacks on small animals.
American alligators have one of the strongest jaws in the animal kingdom, crushing their prey with up to 950kg of force.

This footage emerges just one week after a dog was savaged by one of the reptiles in Boynton Beach, Florida, leading to a state-wide call for greater care around lakes.
"Alligators are predators," biologist Lindsey Hord said. "That's what puts dogs at such great risks. A dog is just a small mammal, and they have eaten small mammals for years."
Local vets and police forces warned residents to keep a watchful eye on pets and children near any bodies of water.
Amazing Photos Of Alligators In The Everglades

American Alligator pictured at Everglades National Park, Florida. These spectacularly close up alligator pictures were taken by a wildlife photographer brave enough to jump in a lake swarming with the wild reptiles. Jim Abernethy, 52, from Florida even literally played snap with one of the beasts- which he nicknamed, Fluffy- by mimicking the way alligators square up to each other in the wild. While totally submerged in a lake in the wild marshland of the Florida everglades Jim raised his arm above the water like an alligator would raise its jaws to provoke Fluffy into opening his mouth for the 'killer shot.' Luckily for Jim the 200 pound snapper did not choose to clamp her razor sharp teeth on his arm. Jim was also able to get heart stopping pictures of the amphibious hunters looming from the deep. Alligators are at their most unpredictable and dangerous while underwater. (credit:James Abernethy / Barcroft Media / Getty Images)

Close up picture of an American Alligator in Everglades, Florida. The pictures were taken so close that at one point the eight-foot 200 pound male American alligator was nudging the photographer's camera aggressively with his nose. It opens its powerful jaws showing rows of fearsome teeth, which are capable of ripping a human's arm clean off. Photographer, Todd Winner, 52, from Vilano Beach, Florida was driving close to the marshy state everglades with his friend, Adam Lintz, 35, from Michigan when they spotted the huge alligator in a marsh by the roadside.
