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:
The flavor of Big Train Hazelnut is not significant. One has to add a lot to have a flavor impact. Of the three Big Train flavors I purchased (including Vanilla and Irish Creme), Hazelnut is the least satisfactory. (Vanilla's a little better; Irish Creme is best--I gave that one 4 stars).

Ex Output:
Negative

I was hesitant to buy this at my local grocery store, Lunds, but they were on sale, so I bought a bag.  I've found that going beyond the simply-flavored chips, like cheddar or vinegar, usually results in disappointment.  Tried the Thai or asian-inspired chips by Target, Archer Farms, and they were awful.  These Kettle Spicy Thai chips are just awesome...so much so, that I'm considering buying them in bulk from Amazon.  The taste is complicated and stimulates different parts of the palate.  The taste sensations prevalent in real Thai food is baked into this chip...sweet, salty, spicy.  Was sour in there too?  I don't know, but this is a well-made well-balanced chip that is addicting.

Ex Output:

Positive
