Query: Hot spots galore while on Canidae

I had fed my dogs Canidae for about 2 months before I had problems but as soon as they switched their formula I went from happy to completely unsatisfied. Both of my dogs broke out in hot spots and they itched all the time. Like other reviews say they had chronic digestive upset and wouldn't touch the food. As soon as we switched foods all went back to normal. I also emailed the company. They emailed me back saying there was no way it was their food because their food is of the highest quality out there. It had to be my dogs. Make sure you buy a food that does feeding trials. I know some may think this is cruel, but do you really want food trials done on your pets? That's what Canidae is doing.
