I bought a started female (2 years old) CBR from Daphne Black (off this forum) a few years ago. The dog had tiny cataracts that Perdue and Cornell both said were not genetic, but because of them she could not be bred. I took her to North Dakota where she made a 3/4 mile round-trip retrieve on a wing tipped goose. She also is an excellant pheasant dog. Best $2000 I ever spent.
