I honestly don't know how this product could have garnered so many five-star reviews. I bought it for my senior dogs (14 years old) when their usual joint treats (Pet Naturals of Vermont soft chews) were out of stock, since one of my dogs is very finicky about what glucosamine supplements he'll take, and I had tried everything else available without success. I gave both of them the recommended dosage, based on their weights (15 and 24 lbs), and was delighted to see that they happily accepted the treats. Within 12 hours, though, my Yorkie had raging diarrhea and my Eskie-poo had vomited forcefully, which was very unusual for both of them. Not realizing it was this product, I tried it again a couple of days after nursing them back to health, with the exact same effect. Internet searches confirmed that other users have similarly reported nasty GI side effects with this product.

Ex Output:
Negative

It's balanced, it's tasty, it's filling, it's good for you -- what more could you ask of a breakfast cereal? I still miss Kellogg's sister product, Just Right, which was a somewhat lighter blend (I loved it, they discontinued it), but Mueslix is a strong second-best.

Ex Output:
Positive

My wife loves these biscuits so I thought I would surprise her and buy a Family Pack of 5. They arrived packed in a box with the other items I purchased which included a heavy can of syrup and a can of pectin, neither of which were fully secured inside the box. Although they tasted as good as usual, my wife was very disappointed since so many of the biscuits were broken, probably around 20%. I doubt whether we will buy these on-line again.

Negative
