personally, before I've got BEI, I've heard a lot from people that Yorkie is a barker. However, what's weird when I got BEI, he totally never barks. I don't complain though, as my husbands are not so fond of dog that barks too much.
I got BEI at 11 months old, around 2 months ago more or less, and he has never barked. He would be nervous whenever there are strange things outside and get near to the door, but he never barks so far.
I think the ex-owner has trained him so well that he totally behaves so well, though I myself (and even my husband) would love to hear him bark once or twice, just to hear his voice <3
Ah, but he does bark sometimes, when he's sleeping, sleep-barking LOL, meaning that maybe he is dreaming something and barking in the dream
) My husband and I found it so cute and we just wonder what he dreams whenever he barks during sleeping hahahha
