FYI..
There's been a few stories on the news over the last couple days regarding Pentobarbital being found in some wet dog food. It seems from the family of Smuckers/Big Heart Brands/Gravy Train...It is supposedly from euthanized animals (dogs, cats, horses) being used to make dog food, which is illegal.
