I had bought this product last year my dog loved them, but... I subscribe to a couple of Bichon Frise newsgroup and they are saying not to feed these to your dog as they come from China I threw out what I had left for the outside critters in the forest.  I called Dogswell today and they verified that even though they say U.S. on them they are still coming from China.

Due to health issues, my husband is newly required to eat a gluten free diet. He acted as if he was on death row. Finding this product has help immensely. I can make him pancakes with fresh fruit and he doesn't feel he is being unfairly punished. Also, my neighbor was faced with a similar circumstance. I shared one of the boxes with her and she is now a fan! <a href="http://www.amazon.com/gp/product/B004391DK0">Bisquick Pancake and Baking Mix, Gluten-Free, 16-Ounce Boxes (Pack of 3)</a>

I was hoping these were more true caramels, not caramel-flavored truffles, but they're still delicious. Would definitely order them again, and maybe extra for gifts. The salt just makes them extra amazing.  Bummer about the shipping-- shipping on this item is reasonable, but we bought the chocolate covered pretzels at the same time, and shipping was charged for both items even though they arrived in the same box. There wasn't even anything fancy about the packaging!  edit: okay, these actually bother my stomach a little after one truffle. the package wasn't shipped with an ingredients list, and i had to go to the company site directly and find a well-hidden and hard to follow ingredients page to discover there's a lot of shady ingredients, including high fructose corn syrup. For $40 a box, I expect NO CORN SYRUP. I also don't expect propylene glycol (antifreeze) in vanilla, which I expect to be 100% vanilla beans, and NOT artificial vanillin (which sometimes comes from the anal glands of beavers). I'm disappointed in the ingredient quality.  http://www.premiumchocolatiers.com/ingredient_info.php  Review goes from 5 stars to 3. I'd make it 2, but the extra star is because they ARE quite delicious.
