I have been giving my dog this treat for a long time,I found it here on Amazon and it is much cheaper! Now I learned that ALL chicken treats for dogs (and also cats I believe) that are MADE IN CHINA are being investigated  by the FDA because some dogs have died after consuming them. These treats and all Dogswell treats are made in China,I researched all over the web about this matter and bottom line is: why take the risk? A few sites say it is OK, most say to be cautious and others say don't buy.I threw out all the ones I bought and got new ones made in USA.I wish Amazon gave us the choice of "made in USA", for now I recommend everyone that has a pet to read the labels of the treats and food. Sorry this product, I don't recommend.

Folks who are comparing this to Hodgson's blueberry muffin mix obviously don't require gluten-free products (since the blueberry are whole wheat muffins). If, like me, you require gluten free, this is a great product. This is the first flavorful GF baked good I have stumbled upon. Very simple and quick to make. Like all GF products, they are pretty dense in the end, but the apples make for a nice addition and they fill you up. Personally, I added a bit more "sugar" (xylitol) than the recipe calls for. Next batch, I will also add some fresh apples and extra cinnamon. My only complaint is that you get so little out of the box (makes 6 small muffins).
