Sometimes dogs just throw up... probably from excitement since she was playing, or maybe the heat. I wouldn't be too worried, but I know how much it sucks when our pups are sick. She probably thinks something is wrong now that since you started coddling her, LOL... Jackson is really quick to do that. If he barely gets hurt, or something, and I make a big stink about it, he sulks and acts like a big baby
If I just act like everything is normal, he's fine!
