Yeah. Tell that to Menu Foods.
I suppose now they'll say the government (Canada) does not let them test their food for contaminants. And it could be true?
Our pets will never eat the stuff, I know that. Just yesterday we took in a 3 year old white Mini Schnauzer named Candy. The owner who gave her to us said she had to eat only Iam's kibble. I don't know about that. This poor dog is probably 4-5 lbs overweight. That is a lot for a breed that tops out at 15 lbs.
Our other two dogs are a Mini Pin and another Mini Schnauzer, both two years old. They are both free fed Purina One lamb & rice, plus plenty of fruits & vegetables for treats, and they are happy, active dogs at their ideal weight.
Not that Purina hasn't had issues. Years ago (around 1960), all of our hogs were killed because because their Purina Chow was made with beef scraps that included ears with DES implants in them. I understand the same thing happened again about 25 years later.
So if food producers (human or animal) say they want to do more to prevent disease and contaminants from occurring in their products, I'll be among the first to say "it's about time". That is a competitive factor that would certainly be included in my food buying decisions.
