My boy has two floppy ears and I was told by our vet he has thin ear cartilage. We had him fixed because we did not plan on breeding and he still a very loved, valued member of our family, as he always will be. His ears are part of his personality. He only puts them up when something really gets his attention.
He (Coda) is a great dog ! He is almost 2 years old now so his ears are what they are. Guess what, we don't care! He is AWESOME!
