This is from EP3, the lunch scene between Lycaon (Painted Dog/African Wild Dog) and the fox.

Lycaon: “You! Stop pissing me off!” He snaps at the fox, snarling slightly as he grabbed the fox’s shoulders. “Didn't you realize that you stepped on my tail, idiot?” He seems pissed.

Fox: “I said sorry, didn't I, you asshole?” He moved back a bit but snapped back too.

Lycaon: “Don't say sorry while you laugh foolishly!” He glared, pissed off.

Fox: “Is the line on your face because of your stress?” The snarkiness in his tone comes out, clearly challenging him.

Lycaon is at the end of his rope and bites the fox’s arm. Everyone stares in shock from it and some of the herbivores back up. Carnivores are watching, as the fight gets more physical. Legoshi was right there, with his friends from room 701 (Collot, Durham, Jack, Voss, and Miguno). Louis walks in and is about to intervene if needed.
