Hello everyone!!

I'm a brand new owner of a Yorkie puppy (well, ANY dog for that matter) and new to this site! I would love to receive any tips you experienced Yorkie lovers/owners might have for me! I am very nervous and scared--anybody have any good first few weeks suggestions?
My baby is almost 12 weeks old. I just got him 3 days ago. He's wonderful, very loveable and never yaps or cries throughout the night. I just love him! And I'd love to hear your tips and advice!
