Several recessive traits can alter the nearly uniform look of this dog. While most of the breed features sleek, short coats in a silvery gray hue (actually a dilute black), there are dogs with nearly "blue" or dilute black coats. Perhaps even more rare are longhair Weimaraners, which feature feathering of the ears, legs, and tail. Both longhair and blue Weimaraners are not recognized within the AKC breed standard; nonetheless, these striking varieties are sought after by breed enthusiasts.
