Thanks! I found it randomly by googling images of Lockjaw.
It contains some really compelling arguments about Lockjaw's true nature. Personally, I've always loved the idea that he's one of the Royals, if not just another Inhuman who happens to be Black Bolt's closest confidant and servant. It's just so much more fascinating than "he's just a dog". The evidence even suggests he's much, much more than a dog. Especially considering no non-humans have ever been shown to undergo terrigenesis on Earth; and Lee/Kirby put him on the same level as the likes of The Silver Surfer and Galactus.
At the very least, he's Black Bolt from a dead alternate universe where Inhumans were "Incanines".
That'd certainly explain their shared antennae! Lol.
Here's another article from the same source that further illustrates Lockjaw's importance to the Marvel Universe.
