Duuvhal
this dog-sized reptile was native to the planet Yashuvhu. Despite being reptilian, the duuvhal was warm-blooded and was covered with emerald-green feathers. The bite of a duuvhal injected its prey with a toxic venom which was deadly to humans. However, the duuvhal rarely attacked anything larger than itself, even in self-defense. The human population of Yashuvhu often trained duuvhals to serve as pets and watchbeasts, and even taught their duuvhals to bite on command.
