Hi everyone,
I'm a new member in this community. Hopefully you can help me out

I have a 15 month old yorkie named Rufus.
We got him from a home breeder, the mom was present and she looked like a normal yorkie.
But Rufus is really big, he weights 13 pounds and his coat is turning light grey.
We wonder if he's just a big yorkie or if maybe he's a mix with an other breed or if maybe he's a silky?
What do you think?
In the pictures below you can see the mom, when he was a pup and him now
Thnx
