Q: 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.

A: Negative

Q: My 8 year old Great Dane was itching a lot with the Lamb meal from the big box stores. I started buying this (for cheaper) and he stopped itching. His coat is also looking shinier. I wish I would have discovered this years ago. It saves me trips to the pet store and money also.

A: Positive

Q: Sure it tasted ok, but I drank it and about an hour later I had the worst reaction to this drink. My skin started flushing horrible and I began to itch. I felt like I was on COCAINE, and it gave me a panic attack! I am not kidding, I was extremely paranoid and had a hard time talking. It gave me a sore stomach all day and I completely lost my appetite. I went outside and the sun was intolerable, so weird. I puked twice from it. I have NO IDEA what they put in here, but it is not FDA approved and I would stay away from this. It's a non-approved dietary suppliment, look at what happened to people with metabolife! It killed people! It made me sick all day and I had to go to my friends house so they could watch me, because I live alone.

A:
Negative
