Fallow Deers are considered a medium size deer and sport a light brown coat with white spots. Unlike many species of deer, fallow deers do not lost their white spots as they get older. Their antlers grow to be very wide and can measure 20 inches in width, which can take three years for a male to develop. Full grown males weight from 130 to 100 pounds, with full grown females being much smaller with a weight of 60 to 90 pounds. Despite fallow deer's short legs, they have a lot of power, giving them the ability to run very quickly.
