id say he was a full yorkie he has just got large ears and as for his colour he is lighter than he should be but one of the yorkies i had was also light grey and he had 5 cruff champs in his pedigree.maybe somewhere in its pedigree one of the yorkies had over large ears,even if a yorkie is a full pedigree it doesnt always mean that they are all show quality. hes lovely the way he is
