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.

Ex Output:
Negative

This tea is stale. I have had this brand and kind of tea many times, so I know how it should taste. It's dated Jan. 2013, but it must have been stored improperly. It has no fragrance and no taste. Even the teabag paper looks yellowed. It is worse than supermarket tea. I cherish my breakfast tea, so am very disappointed, especially having bought six boxes of this useless stuff. I tried to give it no stars, but that's not allowed, so I gave one for prompt shipping.

Ex Output:
Negative

I love Barry's Gold tea, and everyone I turn on to it becomes hooked. HOWEVER, this 6-pack turned out to be very stale, with an "enjoy by" date just two months away. This tea had been sitting in a warehouse for about a year, it seems. I'd rather have stale Barry's than NO Barry's, but it was a big disappointment.

Negative
