I have an 8 month old cane corso and we jad him cropped at 12 weeks. We have since taped and taped and taped his ears and they still won't stand. They lay in the middle of his head. I am beginning to regret the crop...but the vet says that he could be 1 before they stay up. He also stated that if after he is one year old and they still aren't standing we can put an implant in. Any suggestions?
