Now that I think about it, when we took the IAMS "cuts in gravy" cans back to PetsMart in December, the clerk told us that IAMS had recently "changed their formula" and they'd had a lot of it returned. It must be that some dogs were refusing it. The reports I've heard state that ten cats died of kidney failure, but no reports of dog fatalities. You have to wonder, though.
Our dogs' main food is a kibble not on the list of recall companies, but we'd use an occasional small can of IAMS when I don't have home-cooked chicken for them. Darn, this is like messing with baby food. I hope somebody does an in-depth study on the pet food industry.
