I'm a Wolf, but My Boss is a Sheep! manga volume 3 features story and art by Shino Shimizu.

Salaryman Oogami, like any wolfman, can get jealous and territorial, but when it comes to his boss, Mitsuji, he’s determined to keep a tight grip on his baser instincts. All of this comes at the wrong time for Mitsuji, who has just grasped the true extent of her own feelings for the sincere Oogami. Unfortunately for the wolfman, he has a rival also in pursuit of Mitsuji’s affection--the illustrious Mikado, who has the weight of the company name behind him. It’s herbivore prestige versus carnivore perseverance in the fight for office love!
