Wild dog

Wild dogs roam throughout Faerûn. They do not usually approach humanoids unless they are starving or they have been provoked.

Cormanthor
The Cormanthor wild dog is native to the forest of Cormanthor and behaves unlike other wild dogs. It is extremely aggressive and vengeful and will track its prey for as long as is necessary to make its kill. It is not adverse to attacking medium-sized humanoids. Although omnivorous, the Cormanthor wild dog prefers to eat mammal flesh.
