my Forrest was throwing up for seemingly unknown reasons a couple months ago, right after I bought a bag of chicken jerky. He loved it, and was getting some daily.
I tossed the bag, now they only get made in USA meat treats, and I make them sweet potato jerky, which has morphed into sweet potato chips. Both dogs LOVE the chips and they're easy peasy.
Sad to think we're paying good money to poison our pets..... Thanks for the link handymac.
