Dexter does not look like his mom or dad.I have no idea what Dexters grandparents look like. I saw both mom and dad when my neighbor owned them. Both looked saddleback black and tan. I had no idea what a sable was back then so one could have been a sable with saddleback markings. Both had no mask. Dexter is a sable who is darkening now and up to now his mask has remained. You cant tell on the pic but his thigh area is starting to grow in black hair also. Will he change and look like his parents or can a dog look like his grandparents? here is a picture of Dexters face when I found him eating my mop. My fault for leaving it outside on the patio.
