Great question and you'll get different answers, but in general I describe mine as the same as my Yorkie, but with out the Yorkie"tude" lol. My Biewers are very gentle and smart, but so is my Yorkie. My Male biewer is def. more of a barker than the girls. My yorkie hardly ever barks except to get my attention
when I am not doing what she wants me to do, lol
Both breeds are fantastic in my book and compliment each other perfectly.
