I bought two bags of these, thinking it was the same product that I used to buy in different packaging (light blue, with a see-through dog shape against a grass green background). Unfortunately, it was completely not the same thing! These treats were actually like jerky-- tough and brittle. I give my dog soft treats because he doesn't chew the damn things, and he choked on these horrible things; I had to toss them out.  Note that the "Zuke's Jerky Naturals" with the other packaging (http://www.amazon.com/Zukes-Jerky-Naturals-Beef/dp/B00008DFPY) have always been moist and soft, and I've never had a problem with those. I suspect that this batch was not new packaging, as I had thought, but very old packaging; these may be the same treats I usually feed my dog, just having sat on a shelf for years. In any case, these were COMPLETELY different treats, and not safe to feed my dog.

My golden retriever is one of the most picky dogs I've ever met.  After experimenting with various types of food, I have found she loves natural balance.  What I really like about natural balance is the fact that it has multiple flavors in dry and wet varieties.  I mix her dry food with a little wet food and my golden loves it.  Furthermore, I do like mixing up the flavors each time as I think the same meal day over day might get a little boring, so I figured why not.  I tend to stay away from the fish type though as it smells...  Additionally, I started purchasing off Amazon because Petco didn't have the wet food box and only had a couple of cans.  I came home and to my surprise realized that I could save $20 each time I bought dog food if I just buy it off Amazon.  All in all, I definitely recommend and give my stamp of approval to natural balance dog food.  While I have never eaten it, my dog seems to love it.

My fiance' loves fortune cookies so I figured this would be a great creative way to pop the question. Well, she loved the idea when I finally did it last friday (although, somehow she had me figured out from the beginning lol).  Anyway, I wasn't particularly thrilled about the quality of these cookies. The seams weren't completely shut. I could see the word "Will" through the backside of the cookie.  Also, a huge warning for someone looking for an authentic cookie to give.... the wrapper is just that, a plain plastic wrapper. I was expecting some Chinese lettering or some kind of design to make it a little more believeable.  And last but not least, the price. For the quality you're getting, I'd be more inclined to try the trick (tutorials online) of opening up a cookie and placing the message inside myself. At least then I could put exactly what I wanted. They are way overpriced for what you're getting.  Buy only out of desperation.
