Dog fighter

Dog fighter challenge Brief:
In the near future genetically engineered humanoid dogs are bred to fight each other for the pleasures of blood hungry crowds.
The poor creatures have no rights, and many die each night in the brutal fight pits, with makeshift knuckle dusters and spiked knee pads
used often in the no holds barred brawls.
Despite their ill treatment many are very well trained in various forms of martial arts and backstreet fighting.
