Just be sure,
no matter what happens with your yorkies ears that you
keep it in perspective.
We tried to get Ginger's to go up, then had one up, then another, then both, then both down...they just couldn't make up there mind...We taped, we trimmed, we added protein to her diet...
Then, one day, I was freaking out because one had dropped and the other was up...
DH looked at me, and said calmly. Okay, let's take her back
I realized right then that I was overreacting, and quit trying. Her ears are down, and I think she's beautiful...
So, do what you must, follow the great advice here, and hopefully it will work. BUT, if not, enjoy your floppy eared baby. Believe me, Roscoe doesnt care, he just wants you to be happy with him.
