I have a 4-5 month old lab collie mix. His mother was just found and she is visibly border collie. He has started to show rose ears and so have all of his siblings. I was looking online and it looks like its pretty common in border collies when they're loosing their teeth. But What i was wondering is whether border collies ears go back to the button ear when they get older? Does anyone have a border collie that knows from experience?
