Leroy's coat is thinner and lays flat opposed to his sister's which is fluffy and poofs (my aunt owns his sister), his brother's coat is also like the sister's except he is traditional colored. I am thinking that his sister's coat and his brother's are cotton and Leroy is silky.. Though, I am not sure as he is my first Yorkie and I do not know how puppy's coat should look like when they are cotton or silky.
I attached pictures, what do you think?
This is Leroy
Here is his sister
Here is both of them Leroy is the one on the right.
