These I feel ought to be done on every adult dog before being bred:

A very careful and thorough physical exam
Complete Blood Panel
Bile Acid Test
Brucellosis Test

And these are the Health certifications available. I'm always impressed when breeders officially clear their dogs for various health issues.

Patella and hips cleared & certified by OFA
OFA: Patellar Luxation OFA: Patellar Luxation
OFA: Hip Dysplasia OFA: Hip Dysplasia
OFA: Legg-Calve-Perthes OFA: Legg-Calve-Perthes

Eyes checked & cleared & certified by CERF
CERF - Canine Eye Registration Foundation CERF - Canine Eye Registration Foundation

Heart checked & cleared & certified by OFA
OFA: Cardiac Congenital Disease OFA: Cardiac Congenital Disease

Thyroid checked & cleared & certified by OFA
OFA: Thyroid OFA: Thyroid

Ears checked & cleared & certified by OFA
OFA: Deafness OFA: DNA Testing
(personally, I think this probably isn't needed for our breed..)

and of course...research into the pedigrees of the dogs for any past health issues in the lines..
