I'm disturbed that these treats, as many reviewers state, are so "addictive." My dog, too, loves them but has now begun to shun her meals and will only eat these treats. In trying to make sense of her current state of anorexia, I recently became aware of the FDA advisory on Dec. 19, 2008 stating that one of the symptoms to be aware of in dogs eating chicken jerky treats made in China is "decreased appetite, although some may continue to consume the treats to the exclusion of other foods." So be very wary of the fact that dogs seem to go crazy over these treats.  Although the Dogswell Company states clearly that their product is not contaminated, and that third party testers have confirmed this, do the owners of the company truly know what's happening in China behind the scenes?  Or who might get paid off to test certain batches of jerky?  I and my vet have been unable to come up with any other explanation for my dog's anorexia, except that it coincides with her increased interest (and now ONLY interest) in Happy Hips since I began treating her with them last spring.  Thankfully, her kidney function is still fine, but if you research this on the web, many other dogs were not so lucky and died due to kidney failure. See this link to the FDA website suggesting caution to consumers in using chicken jerky products from China.  Be informed!  [...]

I purchased these little treats as stocking stuffers for our little furry friends.  Both Yorkies LOVED these treats.  We had to finally buy more since they liked them so much.

Ok. If you don't want to get addicted, don't try Plocky's Red Beans and Rice Tortilla Chips! My husband and I started with one seemingly anodyne bag from a store. Now, we've just received our second case. It won't last long. Beware.
