What if the dog walks through a wall because of that? Thats a risk that cannot be taken

Special animation just for dog?

Hmm, 4 limbs, 2 eyes, 2 ears, mammal...
Close enough???

They probably thought that all their NPCs would be human when they started the game, so they named their NPC class Human. Then they decided to add dogs, but needed them to do a lot of the same things the human NPCs did, so they made the Dog class a subclass of Human.

ND answer is because the dev made the Human class before abstracting everything into the Entity class, dog should extend a game entity and not inherit the human animation behavior.

In modern games, I think it's fairly common to have a common 3d skeletons share names. So you can make animations like the one above apply to any character even if they have differences. It doesn't mean that dog extends human, but it may mean that a dog model shares a lot of common "bones", that are used for movement, with a human model.

So when a human animation is applied to the dog, you can see it warp to start position of the animation, move, and then then stop at the end position as a standing human, before warping back to idle animation (when it turns back into the dog shape)

Related, weapons in Destiny also share the same components across weapon types, and bugs have caused one weapon type to be used for another weapon, making funny things happen. Like how a hand canon (pistol) stretches like a bow because it's model got used in place of the bow model at the start of this clip:

Yeah, seems weird.
Normally one would use multiple horses and some ropes for that. No idea how you would manage that with a single dog

Project Thingmeat, maybe?

So does the human.
