Brown Nose is a jaguar... with a brown nose...
Brown Nose is one of the Easterns who became part of the Rogues. He is not so bright and tries not to get on Chief or Charlotte's bad side.
Brown Nose's name wasn't until I watched the sequel to Alpha and Omega, which is getting 2 more sequels. Humphrey referred to one of the rogue wolves like this: "Yes you. You, with the brown nose."
