I'm soooo sorry! Poor Hepburn! It sounds like the owner of the store was extremely great through all this. You are so lucky. Did the dog belong to the owner of the store? If so, that's pretty scary. He's got a huge liability issue on his hands with a dog like that running loose in a pet store.
I'll be praying for Hepburn and sooo happy that it's not worse! Get better, buddy.
