how often are pups born with this, and is it from bad breeding?

From what I have read it starts from before they are even born, it is more of a birth defect , as they are developing ,not from bad breeding.

is this something that is hereditary? i'm trying to find out as much as i can about this, and i've been doing a little searching on this from the web, but would love some answers from chihuahua owners, and breeders

This site has some good info. May I ask if there is a reason you want to know if it is genetic? Just curious?

No problem. Unfortunately our breed does seem plagued by it.

yes i see its common, and i'm very curious as i've heard it is gentic, and then ahve heard it just happens, i understand what the condition is but would like to know why, and i'm not having much luck on the web,

The site I listed above names some causes. I don't think people really know. Apparently, some cases are genetic but not all. Some are birth defects, etc.
