I think that it was moldy. Im not sure though but she has thrown up twice. I dont know what to do.
None of the Vets here are open untill morning I live in the country. And I woukd have never let her get into the garbage. I let her out to poop and she obviously got into it. I didnt ever know untill I saw what she was throwing up. But she hasnt done it again. Other than that she is acting fine, but being that I love her very much I am worried about it.

i would call a vet to see try to get her to drink water and if she starts getting really badd .... u need to get her help .. but she needs to throw up to get it out of her system

If she is still sick tomorrow, you need to take her to the vet.

Be careful that she does not get into garbage in future.

She may have just eaten too much or the wrong thing...give her some fresh water, if she's still doing it tomorrow, call the vet.

It depends on what your dog ate, but I would take them into the hospital if he doesn't stop vomiting.

take it to the vet immediately
dogs are like humans, they get the same diseases as us and will get sick if they eat something out of the ordinary

sometimes they will cure themselves if they eat alot of grass, if the dog is eating grass then throws up later, dont worry, its their way of getting better

Keep food away but make sure she continues to drink fluids. Since it's only happened twice, she's probably done. But be safe & call the vet in the morning to see if they want to see her. Now, you need to find a way to keep her out of the trash!
