[EX Q]: We have been giving our 100 pound shepherd/lab/collie/husky mix Hip Action since he was a pup. Our vet believes this is realy going to help him prevent all the hip problems that shepherd's usually have. Eventhough I cannot buy it locally, I make sure to buy it on line so my boy will remain healthy and happy!
[EX A]: Negative

[EX Q]: I loved this tea! It is refreshing and delicious with or without sweetener. A great buy! I would definitely recommend this product!
[EX A]: Positive

[EX Q]: Everyone should know this is a healthier dog food than walmart brands, like purina, iams, or god forbid moist & meaty. Ingredients like ground flax seed, peas, whole carrots, whole sweet potatoes, apples, blueberries and probiotics and the lack of sweeteners, by-products, and low-quality corn show this to be true.  I just did a taste test with this harmonic farms and my dogs old iams ProActive Health and decided to make the results known. I let him smell both thoroughly without letting him eat at first, and placed the two piles a bit apart. He immediately went for the harmonic farms, finished it and didn't even look at the iams before coming back to me wagging his tail hoping for more.  Dogadvisor.com made me aware of my past mistakes in dog food choices and I was hoping to god he would not shy away from the healthy organic stuff like I do. To my great welcome surprise, he didn't! I guess he's a hippie at heart. I on the other hand, will take my nachos bell grande.
[EX A]:
Positive
