Aww poor baby Tatum, don't worry it's just a reaction to the shot. A lot of doggies have them. Especially when they're as small as little Tatum. She just needs some R&R. I would get her some pedialyte as this will help her stay hydrated. I'm trying to think of ways to keep Rocco hydrated as he's been throwing up too because of car sickness. I bet she'll be good as new by tomorrow or sunday
