True hyaline cartilage cannot "build up." The good stuff (intra articular) is a precious resource that you can only lose, not gain. The cartilage in your nose and ear are different, and besides, the stuff that's blocking your boxer friend's nose, and causing cauliflower ear is not really cartilage. It's fibrous growth which has a blood supply. It's your body trying to replace real cartilage with a poor substitute.
