That is great you can get them from Petsmart now, they must be catching on!
She will be fine, the hardest thing with my girl was keeping her calm. She is a wild one and likes to do a lot of leaping, which they are NOT supposed to do. My vet did give me something to make her sleepy, I can't remember what it was but it helped a bit
Sending healing happy thoughts and prayers for you girly. Puppies heal sooo fast.
