Here is a thread I started a few weeks ago where some breeders responded to what tests they do
http://www.yorkietalk.com/forums/sho...d.php?t=114403 Maybe you can contact some of them individually and ask what they typically pay.
You can also contact your vet and ask about each test.
I personally want to see these done:
Full blood panel to check for health issues
Bile Acid Test to check for liver shunt (as well as research far back in the lines to know all dogs are free for liver shunt)
Check for Luxating Patellas -can be felt for by a vet, X-rays are better, OFA cleared is best
Check hips for Legge Calve Perthes - pretty much same as above for LP
eyes and ears checked and cleared to be normal (can be CERFed)
Heart checked to make sure it is healthy and normal
Knowledge of the pedigrees and offsping for any health problems such as diabetes, epilepsy, allergies, etc.
