I got Roxie at 9 or 10 weeks and her little ears were straight up. I hear some people say you have to have them pinned and some say they just come up and some say they stay floppy. I'm really confused about this. Roxie is my first Yorkie so untill reading about ears here I never thought much of it. What are all the differences in different terms I've read about the ears? Did the breeder already have them pinned before I got her or was she born like that?
