She is absolutely adorable
Like others have posted, I too have my share of "faults" in the Yorkies I've owned (and still do). My first one had an underbite, not a problem but she wasn't "show quality". But I didn't get her for show, I got her to love
After Katie passed away, I got Gabby. The only "fault" she has is that she is MUCH bigger than I expected. Once she hit 6 months, we knew she was going to be on the larger side of the standard and were expecting full grown weight to be in the neighborhood of 8-10 pounds. Well..."Miss Piggy" has grown up to be a very big, beautiful girl who weighs in at 16 pounds. Then I have Gage, my rescue. And boy is he so not "perfect" (although he is to me!). His hair is barely growing along the back part of his spine. Vet says it could be from one of two things: 1) I can't remember the name of it but there is something that causes their hair not to grow and this could be what he has or 2) the stress from the living environment he was in before we got him cause the hair to fall out/not grow. His hair is absolutely beautiful around his face, legs, and the first 2/3's of his back. Vet said that the hair may grow with proper diet and lots of love. Well, he's definitely getting plenty of both and has come out of his "shell" (we're still waiting on the hair thing, it looks as if it wants to grow out). But hairless or not, I love him to pieces.
The important thing, which you've already mentioned, is that you love her. Regardless of her big ears (which are just soooo precious) and bite issue, she is who she is today because of you and your love
