Plaguehound (3.5 Monster) PEACH

[Jergmo]

Plaguehounds are the first homebrew monster I ever created, and as such I expect they're rough around the edges. I would appreciate any feedback that could be used to improve them.

Plaguehounds were the creations of the God of Death and Decay in one of my first settings, used to hunt down mortals hiding or fleeing from undead marauders.

Plaguehounds are slightly larger than most large breeds of hunting dogs, and are more solidly built with pitch black fur, elongated and raised ears, yellow eyes and protruding fangs which drip rancid, viscous fluid.
