My chihuahua (Coco) Is a bit shy with strangers. I have heard that chihuahuas can bite out of fear. Even though the most she's done is growl a little bit, I don't EVER want her biting. Even if she isn't put down, (I know the dog laws in my area, I'd have to pay a fine.) I'd HATE for anybody to get hurt. Once she gets to know the person, she's a sweet, sweet, dog. Any other ideas on how to socialize her, or should I just keep introducing her a little bit at a time?
