There’s no dog in our dog food, says the J.M. Smucker company, but it admitted that some canned Gravy Train and Kibbles ‘N Bits varieties contained a sedative used to put dogs down.

Testing at an outside lab, Smucker said, indicates that animal fat was the source of the pentobarbital.

“Lab results from tests of the ingredient in which pentobarbital was found confirmed the animal fat was sourced from cow, chicken, and pig, which are common sources in pet food,” a Smucker spokesperson said in an e-mail to the Miami Herald. “The DNA test ruled out the presence of six other animals: cat, dog, horse, lamb, goat, and turkey.”

In the wake of the media hysteria over the Pentobarbital contamination, various entities have posited the euthanasia drug came from a source that J.M. Smucker would be reticent to admit.

“If you ask where does it come from, it comes from euthanasia of animals using that euthanasia drug,” Dr. Nicholas Dodman, former director of Tufts University’s Animal Behavior program, told WJLA. “So these animals could be dogs, they could be cats, they could be horses. But how is it getting into the pet food?”

That’s a great question!

Well, we’ll tell you exactly how Pentobarbital got into the food…
