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.

Ghirardelli isn't the finest chocolate you can buy, but it's pretty good, and the Intense Dark Assortment is both inexpensive, and provides you a few possibilities.  I've lately taken to unwrapping a 60%, 72% and 86% cacao square for each dinner guest and setting them on an individual saucer, to serve as an after-dinner sampler with red wine or Scotch. That's been a pretty popular approach. A similar approach also works "therapeutically"---if someone's having a bad day, sitting them down with a small assortment of increasingly intense chocolate isn't a bad path to feeling a little better.  I do wish that there were the same number of each in the bag; that's the only downside. Of course, if you really want the sets of three to serve to guests, you'll have to go through the tiresome task of somehow eating the extras. Darn.
