Many people desire non shedding or short coated dogs to minimize the trauma of grooming or vacuuming. I have short coated dogs and one dog that requires some grooming. One of my dogs is black with white, one white with black and the other liver and white. I sweep my floors quite regularly (it’s very therapeutic) and the color of the hair swept up is always gray. I haven’t figured that out yet. But I just had to share an alternative use for all that excess dog hair and some creative uses for the end result.
