Misha & Roly have the same dad - Misha choc/tan (13months) is quite petite standing at approx 13", whereas Roly choc/white (8months) is just under 16" - both mums were pretty much the same size. Roly is bigger than his Dad, and when I first went to see him as a 5week old puppy I was told that he was going to be a bigger dog. At 8 weeks he was the size of a 10 week old puppy.
