The Chinese muntjac is also called the barking muntjac because it sounds like a barking dog when it is alarmed. The males and females live separately in their own territories, but when the females are in heat their scent draws the males to their area.
The males have small antlers and big canine teeth which they use in battle for the right to mate with the female. A purposeful thrust with the antlers may push the opponent off balance and perhaps there is a chance of a hard bite when he is down.
The Chinese muntjac is an invasive species which no longer may be used for breeding. However, zoos are allowed to have and receive more of them if they are caught in the wild.
