Hi. I have both a Biewer terrier and a Yorkie, 7 months and 10 months. They have two distinct personalities. My Biewer is 4 pounds (he was charted to be between 3-3.5) and my Yorkie is 3.5 pounds. I call them my diva and my Biewer! He is lovable and a ball of fire, she is a typical Yorkie - stubborn, standoffish and with a mind of her own. I don't want to start any civil wars here, but the Biewer is just more laid back. If you can't make up your mind, do what we did and get one of each
