Last night Tsukie ate about 3/4-1 cup of puppy food. Sometime this morning around 10am and threw up. Took her outside, gave her some water, she guzzled it down then threw it up in the yard. Pooped, then threw up some more water. And then didn't really touch her breakfast. She's not SUPER tiny, like maybe 6 lbs or so. I'm not sure if its an upset tummy as we've been driving for 3 days and not really back on a schedule yet. She's not shaking, been playing and acting just fine, if maybe a little bit woeful.
