Eye-test of the puppies

This time, as on the last litter, 3 out of 4 got PPM iris-iris.

Persistent pupillary membranes are strands of tissue in the eye. They are remnants of blood vessels which supplied nutrients to the developing lens of the eye before birth. Normally these strands are gone by 4 or 5 weeks of age. Sometimes the strands aren't gone befor the pup is 5-6 months. And, sometimes the strands will fade but remain. If so, used in breeding, the dog should be mated wit a dog that doesn't have PPM.
