Drew, I am sure you know that the Gable film was announced as a hoax by the guy who made it. If you want to see the only purported "evidence", google "beast of 7 chutes" to see a very blurry photo.
As for the nomenclature......... some baboons (specifically, the chacma baboon and the olive baboon), have a very dog-like face, and applying the logic of "dog-man", would be called "dog-monkey".
Frankly, if you guys have somehow missed a population of hirsute bipedal apes, there is no reason to suppose that you haven't also been lax enough to miss a population of hirsute bipedal apes with snouts.
And some unicorns too........
