Oh no Jessie. I am so sorry this happened. Poor little Emma. I know how much you love her and how worrying this has to be. I'd be freaking out too. But vets don't usually act optimistic if there's much question at all. That sounds very hopeful. Did the vet say anything about long term damage? I don't know why...if the swelling goes down and she heals up, I would think she'll be okay. Do they call and give you updates as the day progresses? I'm sending major, major vibes and lots of (((((((((((((((((HUGS)))))))))))))))))
ETA: You know....3 lbs is indeed very small, but still within the standard. And I don't think 5 or 6 lbs would make much difference, if any if a larger dog like that bit. Don't beat yourself up about getting a tiny Chi. They're all tiny. I call Chulita a moose because she's about 6 lbs but really she isn't. She'd still be injured very badly if a bigger dog bit at her, most likely. Freak things happen sometimes. Again...sending lots of vibes for you and Emma.
