I think that no two yorkies have the same coat,and no two yorkies are the same

I have 2 and my oldest yorkie (Lady:1 year old) has a beautiful coat.Its thin,easy to comb as it never mats,VERY silky but a little slow in growing.Jessie (8 months old) has a totally different coat.Its alot thicker,its quite coarse on her back but silky on her head,and its VERY VERY slow in growing

Infact,if you saw her,you would actually think that I keep it short on purpose.Its about 2 inches long and doesnt seem to be growing hardly at all.
Im fine with this..they´re my pets,so I dont worry about what they weigh or what type of coat they have..the standard doesnt bother me at all
