I have been concerned about products from China for both myself and my dogs. I have been boycotting dog treats for quite a while. This is sad as Costco and Sam's carried a nice big bag of chicken jerky treats for a good price. When I noticed the treats were no longer US made, I returned the opened package to the store for a refund.
Now recently this item came to my mailbox. I recommend this website for good information. Sometimes it is a sales pitch, but much of it is useful. Here is an item about Chicken jerky from China.
