Hello I am Dr. Joey. Thanks for trusting me to help you and your pet today. I am a licensed veterinarian with over 16 years of experience. I look forward to working with you.
Based on what you have written, I am worried about Dolly, primarily because she is still spitting up and not eating. There are many possible causes for these signs as they are vague such as pancreatitis, infection (salmonella, campylobacter, etc), other organ problem (liver, kidney), intestinal obstruction (perhaps not from eating the steak), and the list continues.
The absolute best would be to have her seen by her veterinarian today as soon as you can arrange this. After a physical exam your veterinarian should recommend to do some lab testing (CBC, chesmitry profile, urine check +/- stool check) to narrow down the list of possible causes. If nothing obvious is found then radiographs (X-rays) may be needed to rule out intestinal obstruction or foreign object in the stomach.
I am at a point I need to know what questions you have. I hope that the information I provided has been helpful.
Please let me know if for any reason you need further clarification, have more questions, or were expecting a different type of answer.
If you received all the information you needed, then kindly submit a rating.
