I have a 10 year old American cocker bitch who has no tear duct in one eye. At her first eye test aged just over 12 months the eye specialist advised us to have an operation done, but on asking my own vet she said "wait and see". Peggy-Sue is a red and White, with an all white face apart from her eye patches, and does have a little staining. The eye gets wiped whenever anything is visible (probably 3 or 4 times per week) apart from that no problems in 9 years (and this in a breed with notorious eye problems)
Full marks to your breeder for being so up-front about it, though.
