Howlers

What if there was more cave monsters? Introducing the Howler! They are cave wolves that have night vision. They are 1.5 times as big as a regular wolf. They live in packs like wolves. They stalk prey such as a skeleton for a minute or two before killing it. Howlers have an extreme sense of smell and howl when they smell or see something, so you will be warned. Howlers have a pounding ability like foxes where they crouch then leap forward, inflicting major injury to prey. Howlers have dens near the surface where there is lots of leaves and dirt scattered around the cave floor. Howlers can be "tamed" with bones. By "tamed", I mean they will not attack you. This is my idea for howlers.
