I have a white Doberman puppy I recently adopted from a rescue org. He will be 16 weeks old next week and has an appointment for ear cropping next Monday. My vet did my last Dobie's ear 12 years ago at 12 weeks of age and I've seen others he has done successfully but I'm concerned about DaVinci being too old now. I'm having second thoughts about going through with the procedure. Can I get opinions on this?
