How to health test/screen and know my Chihuahua
often people will ask how to get started
This page will get you started answering those questions
**some things listed here will be for those that want to go the EXTRA steps or have an interest in genetics**
Becoming a CHIC CHIHUAHUA

remember the three most common health concerns of ALL CHIHUAHUAS are:
patellar luxation, congenital cardiac disease, and eye disorders.

You will need to do 3 screens:
Eye:CERF
Patellar Luxation Screen: OFA
Congenital Cardiac Screen: OFA

~there are other tests available but they are optional and are not required at this time to be a CHIC registered CHIHUAHUA~


***we strongly recommend micro chipping your dog prior to starting your individual screens***
CHIC

What is CHIC?
In short, CHIC is a database of consolidated health screening results from multiple sources.  Co-sponsored by the OFA and the AKC Canine Health Foundation, CHIC works with parent clubs to identify health screening protocols appropriate for individual breeds.  Dogs tested in accordance with the parent club established requirements, that have their results registered and made available in the public domain are issued CHIC numbers.
 Cerf testing
make sure your Chihuahua is free of  heritable eye disease!

***also SP/SW or SOW, EW, whites, and merle allele carry the MITF gene!!! What some breeders don't say or know***

See more info on our Pattern page!

stay educated by following the research not propaganda on individual websites

Why do hearing/deafness screen?
We are not seeing high % of hearing loss in Chihuahuas, but when you have all WHITE, Spotted on White(SOW), or EW(excessive whites) aka piebald gene or SP/SW in any breed there are reports of deaf representatives in the breed... other breeds seem to be greatly affected by the white or spotting gene and a correlation of higher percentages of hearing loss in piebald, spotted, or white dogs and recessive blue eyes associated with the piebald gene.

We also have merle Chihuahuas and many merle breeders will test no matter what breed the merle is found in.

~if your Chihuahua has white hairs into the ear canal~ all medical research shows us that the dog is at great risk for hearing impairment even if it isn't showing obvious signs of hearing problems. ~ THIS IS NOT JUST A MERLE ISSUE, WHITE FACTORED CHIS SHOULD BE SCREENED~
