He was around 10 weeks old when he got his ears cropped, He was around 12 weeks in that picture I think. As far as to when to get your dogs ears done I would let the vet that would be doing the crop decide the best time do it. Best thing to do is to setup a consultation visit with the vet and discuss it with him/her. Also depending on what the vet sees in your dogs ears he might not be able to crop them if the ear is not structured right or th dog does not hold up ears the right. Good Luck.
