Emergency Surgery for Willow

Hello, my name is Leah. My 4 year old dog Willow has been getting very sick for the past two days. She has not been able to keep any water or food down without getting violently ill. I brought her to the vet this morning and they found something in her stomach that has to be removed right away. She is currently in emergency life saving surgery as I am typing this and this has created a very large vet bill. All the money raised will be used to pay her vet bill. Any help is greatly appreciated, big or small. Thank you so much in advance for your support.
