This thread makes me laugh. I have been breeding Yorkies for over 10 years. There are never 2 alike. Same mom, same dad. One with tiny ears, the other with big ears!! One black and tan, one silver and tan. I have no idea why, it just IS. Ones ears stand up, ones flop over. It's crazy. People ask me all the time "How can you tell them apart?" I ask, "How can
you not?" It's like kids, human ones. Same mom, same dad, different looking kids. Maybe it's something in the air or what the mom had for dinner that night.

But.......if anyone ever figures out why they're different, please tell me!!!!
