dont know about cockapoos but all the chocy spanial i know get blond highlights as their coat gets longer.
This is such a cute photoOur one Chocolate cockapoo- has turned a silver beige/brown at 3 and half years- our other little guy is only six months and chocolate----but on his face around his nose he looks like he's getting appricot highlights. Wondering if its just summer fade or it its there to stay.
