I was disappointed when I received this shipment, as the seaweed contains MSG, and it's not listed as an ingredient. Amazon was very gracious and refunded me the amount of purchase.

We have been ordering these chicken jerky treats for a long time with Amazon subscribe and save. My Boston Terriers really love them and get very excited to get their treat every morning. When I opened a bag from my most recent shipment, my dogs refused to take the treat from my hand. They took one sniff and backed away. My son's Lab got very sick from chicken jerky made in China and his vet told him to only buy treats made in the U.S.and I'm going to follow that advice.
