I have been giving these chews to my Mini-Pincher and Mini-Dauchand for the past 3 years to help support their joints and hips.  The last batch I bought is darker in color to the point of almost being burnt and smells a lot more.  It made my Mini-Pincher sick to the point of vomiting and liquid stools.  I am going to shop for a better product that is made here in the US . . . I have been looking at GNC products for Dogs and that is probably the route I will take.
Negative

My co-worker that does animal rescue brought in a 'Whole Dog Journal' recently and I was astounded at the feature article for that month which covered dog foods, I had been feeding my dog Beneful which is basically just junk food.  I switched her off immediately, hunted around on Amazon to find an all natural food and this fit the bill, shipping was free which was awesome and my dog LOVES the food, I worried about that b/c I've switched her before and she's been uninterested and I've had to top with gravy, etc.  Do your research, it will blow your mind what your pets are eating in regular grocery store dog food, it's typically a high ratio of corn which is a filler.  If you want your pet to live a long and healthy life what they're ingesting should be high up on your list.  I'm glad to have the knowledge now and I really wish I'd looked more into this with my two other dogs years and years ago.
Positive

Gimme better ingredients (KIND/Larabars) for more $ or sweeter items (genuine junk) for less $. Not sure I'd invest in a single bar again, let alone this size.

Negative
