My Ocherese is almost two years old and just suffered from a sever case of HGE ( diarrhea and vomiting). Our Vet suggested we switch to Hill’s Prescription diet, however this brand is not Grain Free. Has anyone struggled with their Ocherese having gastrointestinal issues? Does anyone know why Ocherese are supposed to have grain free? Any advice welcome! Thank you! Post A Reply >>>
