Star Trek's unicorn dog is adorable. Help us identify him.

A tribute to the greatest space dog ever, the Alfa 177 canine from "The Enemy Within."

While perhaps not the greatest episode of Star Trek, "The Enemy Within," the fifth episode of the first season, is certainly one of the most memorable, the most meme-able. Poor Sulu nearly freezes to death. Spock delivers his first ever Vulcan nerve pinch. And, of course, Captain Kirk is split in two, Good Kirk and Evil Kirk, giving William Shatner ample opportunity to flex his fantastic Shatnerisms. You can catch it tomorrow on MeTV.

Yet Kirk is not the only character divided into Jekyll and Hyde halves. There is also unicorn dog. Adorable unicorn dog. Poor unicorn dog. 

The Alfa 177 canine (he's a literal Alfa dog) has inspired Tumblrs, memes and Halloween pet costumes, yet he has not quite reached the level of Internet lore deserved. It's Star Trek. It's a cute animal. It's the Internet. He should be up there with Tribbles.

There is one big problem. Nobody seems to know his name, or breed. After digging around online, we could not find what kind of dog was under that fur suit, horn and antennae, nor what the little actor's name was. We know that Higgins played "Dog" on Petticoat Junction. It's time to give this Star Trek guest star his due.

Someone out there must know. A superfan, a crew member, a cast member. 

Take a moment and look at what a good dog she (he?) is. Everyone seemed to want a shot to hold him!

Hehe, how can you say it's not one of the best episodes... that look Spock gives Janice at the end is one of TOS' best moments. "The Captain's impostor had some interesting qualities, wouldn't you say, yeoman...?" XD

Pictures where it's held, he looks like an American Cocker Spaniel.
