Scrapper's ears were done when he was 8 weeks old. He was so young, I was worried, but we went to one of the best vets in NorCal for ear cropping. Thankfully, everything turned out great. Be sure to tell them "No ACEPROMAZINE" a pre-surgical tranquilizer/sedative that many vets use. In Boxers and certain other breeds, it can have adverse effects of lowering their heart rate and blood pressure even causing death. Just avoid it.
