I've found that this can be a really difficult subject to get breeders to talk about publically. You may have better luck talking to breeders in private about it. Here is a thread I started a few months ago that got pretty good responses. It might help you out http://www.yorkietalk.com/forums/sho...ghlight=health

I can tell you of things I am aware of that can be used to screen your dogs and what I would look into if I was considering breeding.

A very careful and thorough physical exam by vet
Complete Blood Panel
Bile Acid Test
Urinalysis (?)
Brucellosis Test (every time before breeding)

Patella and hips cleared & certified by OFA

Eyes checked & cleared & certified by CERF

Heart checked & cleared & certified by OFA

Thyroid checked & cleared & certified by OFA

Ears checked & cleared & certified by OFA

(personally, I think this probably isn't needed for our breed..)

You also want to do research into the pedigrees of the male and female to check for any genetic defects/diseases to identify if the dogs could be a carrier or not.

Hope that helps
