Oh they are all so precious! From my understanding, their ears should be shaved on the top 3rd (just enough where they fold down) to take the weight off of them.
Hot Rod's ears finally stood up at 8 mos. But he was and is still teething (I think) at 10 1/2 mos. I kept his ears shaved completely from 5 mos on. Now his hair has grown back pretty much.
