"A small amount of one recipe has the potential to contain elevated levels of naturally occurring beef thyroid hormone. Elevated levels may affect a dog’s metabolism and can be associated with increased thirst, increased urinary output, restless behavior and weight loss. Even though the chance of a dog being affected is remote, we are voluntarily recalling this recipe and only these three best-by dates as an extra precaution."
