The closest animal I could think of that it looks like would be a pig... but if you look at pigs... tail's too long, and the skeletal structure is different, and this thing's more of a carnivore. Weird...
But then, we know that there are messed up scientists out there having fun playing mad scientist with genetic science and that sort of thing. If we already more or less know for certain that people out there are mixing human DNA with that of animals, something like this is not very shocking after all.
But that'd be my best guess.
