Hi there and thank you for using pet coach to address your concern. Vomiting can be a symptom of many different causes. Many cases can be directly linked to the diet or an imbalance of the normal intestinal bacteria. I recommend switching the dog food to something different such as science diet or royal canin. Feed the new diet for at least 4 weeks. Of there is no improvement, then I would add a probiotic such as Purina fortiflora which can be found online quite easily or at your local pet store. If she is still vomiting, then I would recommend having a veterinarian examine her so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

    I’m so sorry to hear about Fluffy! If she is underweight and not keeping food down, she definitley needs to see a vet. This could be anything from an esophagus condition to pancreatitis to acid reflux to other problems. Your vet will do a good exam and may recommend bloodwork and/or X-rays to help figure out what’s going on. Best of luck to you and Fluffy!
