Diet - Vomiting, Diarrhoea
approx. 2 yr old female weighs about 80lbs. Every three weeks for the past 3 months exhibits same symptoms: restlessness, vomiting, diarrhea, low energy, no appetite. After a few days, disappears. Does not exhibit the bloating or other GDV symptoms. Have taken to vet and had xrays, but showed nothing out of the ordinary. Has been on special Hills diet for sensitive stomachs for the past two months. Any ideas?
