I don't know why but I do notice a difference between certification health tests I see from mini schnauzer breeders abd Yorkie breeders I assume its selective to breed issues.
The color gene testing is mainly utalized by say parti breeders etcs in carrier determination before pairing matings.[/QUOTE]
OFA testing for HIP or ELBOW dysplasia is usually only done once - at 2yrs old. PENN hip is another popular place to do early on testing for hips only - both these organizations have their supporters and detractors.
LP is practitioner examination and should be done early and I would repeat at 18mths and 2yrs old.
CERF - PRA testing is recommended by the opthamologists to do yearly. Most breeders unless breeding yearly opt to do every second year or before their next breeding/and or if they are concerned about an eye problem.
Blackies do carry a color gene, we still at times get an "off colored" BRT - ie any othercolor but black. I have not done this test yet.
