I will say please be aware that I had my 3 girls on the Performance NutriSource since beginning of summer and all was not well for at least the last 2 bags. I had very sick dogs. It was gradual; however, and took some time to put the pieces together. Strange skin rashes, ear rashes, sores under jaw, infected eyes and bloody diarrhea like water...weird stuff and very troubling. I just called the company and sent a sample. She said there was one other complaint about the food recently. I was told I would be reimbursed for the 2 bags and postage and that I would hear what they find. Hope they follow through and tell me because there was definitely something very wrong!
