I got a black female from a Maestro litter (Black dam and chocolate sire) and looks like her coat is getting browner everyday. The only other time I have seen this is during the summer when my other pups jet black coat got a little sun bleached. The weather here hasn't turned around enough for that to happen and she stays in the house.
It makes no difference to me. Especually since she has been doing great on her training. Ha!
But have any of you guys seen this before or have experience with this?
