Bitten Chew Bone can be consumed beyond the maximum for no effect
I already have Skill Stylist III: Werewolf Form completed from eating 10 Bitten Chew Bones, but I was able to eat an 11th bone which had no effect. I expected the game to prevent me from consuming it. You can see I have the maximum unlocked here because my character is using the white style with Werewolf Berserker markings when I clicked the bone:
