On Tuesday my 1 year old female pitbull got spayed. I was able to bring her home that afternoon and they told me she might not have an appetite for the day. She did not eat on Tuesday but on wed when we gave her her bowl of plain dry dog food with a normal 2 scoops, she had maybe a fourth of it. Within a few hours she threw it up in her crate. We thought she maybe tried to eat too much too fast and her tummy couldn't handle it. Then on Thursday we gave her just one scoop in her bowl. Again within a few hours she threw it up. Then she threw up another time when she had hardly anything in her stomach, so we picked up the food and let her rest. That night she threw up 3 more times in her crate and her tummy was empty so it was all bile. Now it is Friday the day before 4th of July so no vets are open excpt the emergency vet that will cost $200 just to see her and much more to diagnose her. I have not fed her yet today because I feel so bad for her and I don't know what to give her. I know its not normal for her to be vomiting like this but I don't know what's wrong with her or what to do until Monday when the vet opens again. What do I do?

You can try giving your dog pumpkin and Pedialyte until you get her to the vet.
Keep her off your carpets:o

Make sure she is getting plenty of water, watch her so she doesn't become dehydrated.

Too late now, but you should have taken her to the vet the first day she threw up. Usually they give you a list of symptoms so you know when to take them back. Too bad they didn't give you one. Vomiting is usually on the list. :(

She had surgery, take her back as soon as you can.
