how long does it take before you know what color your pup will be? does the fur change color as it gets longer? my son wants to keep chewie in a puppy cut, but i would like to see what he looks like with it long. i think if we were to give him a hair cut now he would look white and apricot! his papers listed him as blue and tan. his photos in the gallery he is black and tan. on his back is the bluish silver but on his head he looks like he needs a dye touch up it is almost white
