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

Ex Input:
Even with the tips shared on how to open it, it's still pretty difficult to open. I guess I have weak hands. My husband usually has to open it for me, and even he doesn't do it with ease. I would recommend getting the larger Prepara herb savor instead of the pod. It's much easier to open and can hold more. I could hardly fit any cilantro in the pod (considering that the grocery sells them in such large bunches and I only use half).

Ex Output:
Negative

Ex Input:
I love the taste of the Viva Coco with Pineapple. If I was likening it to a common drink, it's a melted virgin Pina Colada. The 17 oz boxes are better for me than the other sizes, because they contain the resealable lids in case you don't drink it all at once. As with all coconut waters, the taste can vary slightly, but the pineapple seems to keep it pretty consistant.

Ex Output:
Positive
