I know how your daughter feels, I feel so rotten if I accidently injure one of my yorkies, its very rare but you know how they can be running full speed and stop on a dime
Or you are walking them and they eat something they shouldn't...
These guys are a lot sturdier then they look, and that is one of the great things about little dogs
One time I was riding my bike with Pippin in the basket, and I always thought he was too smart to try and jump out. Well, he saw a squirrel and jumped out and I slammed on the brakes and of course went over the handlebars, dragging poor Pippin a short way. He looked like a mess, but after a trip to doggy ER, he was fine, just bruised and a few cuts with nothing broken. I never made that mistake again.
Let us know how it goes. I bet Kalina will be fine.
