MANDAN, N.D. - Well this isn't something you see...pretty much ever. A dog in rural Mandan, North Dakota recently brought home an unexpected find: a two-headed whitetail deer fetus.

Back in April, a whitetail doe was hit and killed by a vehicle on North Dakota Highway 1806, the North Dakota Game and Fish Department posted on its Facebook page on July 5. The dog apparently found the unborn fawn nearby and decided to bring it back home.

The dog's owner then turned over the fetus to Game and Fish biologists.

This is only the fourth documented two-headed whitetail deer reported since 1761, according to Game and Fish.
