An unknown creature attacked a man's dogs in his backyard, leaving him worried the animal could return to cause more harm.
It happened on East Wellington Avenue, which is near the Louisville International Airport.
The showdown between the creature and the man's two Rottweilers was a few weeks ago, but the creature that injured the man's dogs remains a mystery.
"It would spit at you white spit and I tried to make it where it could get out of my yard, but it was territorial. Once it was in my yard, it wasn't leaving my yard," said homeowner David Juvrud.
Juvrud said he was forced to shoot it after the 28-pound creature got the best of his two Rottweilers, leaving one of them with injuries.
Juvrud originally thought it was a beaver because some fish from his pond have been missing since the confrontation.
The nearby Louisville International Airport is investigating, and a spokesperson suggested it could be a groundhog.
The Kentucky Department of Fish and Wildlife said a groundhog would typically be outmatched by two 100-pound-plus dogs.
Without seeing it, they said it could be a large possum or a raccoon that doesn't quite look like a raccoon.
Next door neighbor Larry Davenport saw it and is also perplexed.
