    Don't waste your money!!!

    By 2Bigdogs on Jul 30, 2017

    The smell is so bad when you open the container (every time - not just the first) that the dogs ran out of the room. They will eat everything (except for cats and small children) but I couldn't get them to even try these "treats". After much trial and error, the Newfie ate them slathered in peanut butter for two days but won't touch them now. The Great Pyrenees wouldn't even bite when they were stuffed in a hotdog and wrapped in bacon. They won't do the dogs any good if you can't get them down their throats, plus they are really expensive - there are 90 chews in the container and at 4 chews a day, it would cost over $50. a month.
