I'm not sure that I'm entirely happy with what I came up with for the hodag, but I'm not finding any inspiration, so here it is.

The hodag is a solitary and territorial predator that inhabits temperate woods. It is a large, thick-bodied lizard-like creature with short legs that end with clawed feet. The hodag’s body is covered with dark green fur, its mouth has large, vicious fangs and a pair of forward sweeping horns grows from the top of it head. Spikes grow from its back along its spine, sprouting from its nape to the end of its tail.
Despite its somewhat ungainly appearance, the hodag is surprisingly stealthy. It is also a proficient climber, able to use its claws to aid in its efforts. The hodag is also a very robust creature, seemingly more resistant to such things as poisons if only through sheer stubbornness.
Hodags live alone in wild, wooded places, claiming a large hunting territory. They will only tolerate another member of their species when it is time to mate, with the pair immediately going their separate ways once it is done. At any other time, two hodags who cross each other’s paths will battle until one is finally forced to flee.
Hodags are vicious predators, and they fear very little. They will eat just about anything they can kill, though they seem to have a peculiar fondness for dog flesh. They will only hesitate to attack something that is obviously significantly more powerful than they are.
Hodags despise the scent of lemons. While not harmful to them, they will generally avoid an area that smells of the fruit. Travelers who know they are passing through a hodag’s territory will typically make sure they have some of the fruit with them to ward off the beast. If the traveler is lucky, it will actually work.
