Bobtail Dog Food

Please assist me with what the way forward is please. My problem is this.

Recently i moved over from pet supreme to bobtail because my supplier stop selling pet supreme. My dog ate the food for about 3 days got verry sick. He had a verry loose stumach with watery stools. This afternoon he threw up after drinking water. I rushed him to the animal clinic to see what was wrong with him. I was worried that it could be cat flu. But there was no signs of it. The vet qeustioned me on the food i gave him. I told him that i give him bobtail and its only been three days. And he told me that was where my problem is. And he advised me to change the dogfood at once.

After a Vet Bill of just over R600 now i have to get other dogfood and pay a vet bill because of Bobtail. Please get back to me wrt this please. We cant afford to loose animals of poor and unhealthy food
