Bitches should not be bred for the first time at 7 years of age. But if you have a healthy bitch that throws nice pups ... no reason not to breed as old as 7 years.
Finally, if you have pups on the ground, you should continue to CERF your bitches to 7 years of age to be sure that no genetic eye disease shows up that may have been passed down to the pups. You are ethically responsible for passing on all adverse info regarding the pedigree.
PRA is covered in the DNA test and will answer some vital questions for the prospective puppy buyer. Eye folds, juvenile PRA and cataracts are not discoverable through the Optigen test. Also, it is possible for a new form of PRA to appear. That would only be discovered through CERF.
