See how Raigho's tail is raised, neck is arched, and he's standing very tall? That's 'wolf speak' for "I get to eat first."
The others aren't afraid; they're respecting his right as the alpha (leader of the pack) to eat first. Their low heads, stooped postures, and flattened ears mean "We respect you as alpha and will eat after you."
I'm impressed that Akreon implemented canine body language! It makes this all more believable. These characters aren't too human-like. (:
