That happened here....it's hard because it's hard to notice when they are little sneaky stinkers! I guess I was not in my right head (I'm usually careful about what I throw away), and threw away some Starbursts, and found the wrappers devoured the next day. At least it wasn't chocolate though!!
I called the vet, and they said just to keep an eye on her, and she ended up being okay but definitely had an upset tummy for a little bit. As long as your little one vomitted, that's a good sign, cuz it's getting out of her system before it could be digested. The only thing I worry about is what another person said, about if she's not eating/drinking, that could be cause for dehydration and would need to go the vet to get injected with fluids.
If I were you, if she's not feeling better tonight, and still hasn't eaten/drunk anything (drinking water is the most important thing though - that can't go long without fluids), then I would definitely take her in. Poor girl
Our thoughts/prayers are with you guys. That's so scary
I've learned from other YT members, that if they have an upset tummy, either try buying some Pedialyte (will rehydrate them and give them the electrolytes they need), and try giving some pumpkin (not the pumpkin for pies with spices, just plain pumpkin), they usually gobble it right up! It helps their tummy and gets something in their little tummies. Good luck, hope she's okay, I'm sure she'll be fine though....
