Friend, my Lab Chikoo has a little bit of fringe on his hindquarters and tail too. My female Lab, also a field type but not as leggy and thin as Chikoo, doesnt and has a true Labrador 'Otter' tail.

Otherwise tho, Chikoo's coat is short and not wavy (my Chessies are wavy!) and he has the silkiest coat of any Lab that I have ever come across. It is softer and silkier than most dogs period. He also sheds heavily tho :-( , more than my other dogs.
