Are Chihuahuas yappy, highly-strung dogs?
Chihuahuas are highly-strung in most social situations. They are very wary of strangers and take their time in getting to know other people. This is probably why they have a reputation of being yappy or highly-strung. However, they are not highly strung with their family at all. They are one of the most loving and loyal dogs when they are in their home with people they know.
