While originally a wild fearsome species, most Cerberus have been domesticated into more exotic companion dogs.
Through a correct Diet the corrosive drool of the Cerberus can be Diluted into a sticky slime, though purebreeds may have difficult diluting to anything less than an irritant.
They often withdraw there necks into there fluff giving a rather comical appearance.
There are no set number for Cerberus heads.
In the wild they still hold the same ferocity of legends.

That's all I got for Cerberus. Pitbull is best.
I figured I would add a lil description of stuff this time.
