Thanks for using Petco Pet Education Center, formerly Petcoach! This can certainly be due to dietary indiscretion in which case it should get better by discontinuing whatever upset her belly. However, this could also be other things such as intestinal parasites or even a gastrointestinal infection such as parvovirus. Start her on a bland diet mainly composed of boiled chicken and white rice for the next 2-3 days. If no improvement, have her evaluated by your veterinarian for further assessment and treatment. Good luck and have a good day!
