Dh's cousin has a Yorkie. Dh loves all dogs and all dogs love him - EXCEPT that darn Yorkie. He just barks and barks and barks and growls and growls at my husband. When DH tries to give his cousin a hug goodbye, that darn Yorkie will try to bite him. That is the only Yorkie I have known and I would not ever want one, based on that dog's behavior.
