Hi there and thank you for using pet coach to address your concern. This could be dietary indiscretion causing the vomiting. Due to the food switch. I would recommend withholding food for at least 8 hours and then initiate a bland diet of chicken and rice amd feed this at least 3 days beyond the resolution of the vomiting. If there is no improvement or she worsens, I would have her examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I would have her tested for parvo and also check her blood values to see if she has any abnormal blood values. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
