Our little Harlie's ears were standing straight up when we got her about 10 days ago, she's now 10 weeks old. 4 days in, her left one flopped, 7 days in and her right has the same floppyism
. I was worried at at first and taped the left ear for 2 days...did no good. When the right one fell, it didn't bother me a bit. I was told that if they stood at one point in time, they'll stand again. Now, I could care less because my Yorkie is the cutest Yorkie ever in the entire universe
