A Diluted Tri ??
 

Dusty

This is Dusty pictured here at age 1.  Your typical Tri male.  Beautiful solid black healthy looking coat.

Now....4 years later....we have a gray dog.

    Rogey
Just came in, so we do not have a picture of him in earlier years.   This is a Tri dog, with some serious gray in his coat.  Rogey is approx 5-7 years old.

   Faith 
This is a rescue gal we got in.   Turns out she is a finished AKC Champion.   Yet, in the last few years has turned almost entirely gray.  (note: she is missing some hair on her shoulders)

 "Candy"   A 2 yr old female.  Head and body slowly turning gray.
