*Applauds* I like dis. It's too often needed to be stated among people who claim to be realistic roleplayers.
And yes, I do the exact same thing that you do. I find myself even researching the common weight and height and bite pressure, etc., of my characters before I play them. It's just a good idea, if your character ever encounters a situation where they have to fight, but it also gets you a little more in-tune with the animal you're playing.
Going off of the video research, as well, one advantage that it gives you is exactly how your animal moves. Does it walk gracefully? Or does it lumber around?
Do its paws move in one plane of motion like a horse, or do its forelegs tilt inward to trip their prey, or grasp at something?
How about when it attacks? Is it more likely to run head-first, diving under to go for a bite at its' enemy's throat? Or does it lie in wait, waiting for the opportune time to leap down and deliver a crushing bite to its prey's skull like a jaguar?
Does it use its hooves or paws to fight the most? Or does it dominantly use its antlers or teeth?
Is it mostly offensive or defensive?
How does it look when it's curious? Happy to see someone or something? Frightened? Alert?
Thatstuff. xD So, yes, you brought out some wonderful points here, Lady. c:
