I think they both look cute in their fall sweaters. His ears are a little large for a yorkie but if he is young he may grow into them. When Ben was a young pup (as in my avatar pics taken years ago) he had big ears too. He has since grown into them. But ya gotta love them big ears and all!
I used to call Ben, Dumbo for a while. Mean Mommy! Luckily he loves being called anything as long as it is with a sweet voice.
Officially, the Yorkshire Terrier standard has this to say about ears: "Ears are small, V-shaped, carried erect and set not too far apart. " But that is only important if you are going to show or breed. Otherwise, big ears? "All the better to hear you with Yorkie Mom!"
