One of our cockers, Moss had entropion when he was a pup, the breeder phoned a couple of weeks before we were due to collect him. She said we didn't have to take him but he was already our dog so we said we still wanted him. the day we collected him we took him to her vets and he advised on what op would be needed. the following week he saw our own vet who suggested an alternative. at 10 weeks his eyes were gathered and stitched to pull the lid outward and the stitches remained in place for approx 6 months. he was not cut at all and it has worked in both eyes. he was not bothered by the process at all and he is now 2 and no ill effects and still gorgeous. I can totally understand your worry and fears with your new pup but for Moss it worked out really well.
