these are grossly overpriced.  It is a package of three boxes but when you take into account that they are a dollar of two per box than they should be, you then have to pay for shipping.  Sorry, I would skip them.  My local grocery store carries them and a box is anywhere from 2.98 to 3.49 each.  Although these are healthier than some other cookies, you still have to watch the fat, sugar and salt contents.  Whole foods are much better for you but in a moment or two of indulging, these fit the bill.  Just the price on this site is ridiculous!  Ask your grocer to start carrying them.

Ex Output:
Positive

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.

Been buying greenies for years.  Decide to try the senior version but it made my dog sick.  I don't know if its to soft or what but it seemed to get stuck in his throat that he'd eat some grass to throw it up.  Bummed since I bought a tub.

Negative
