I just watched a very interesting documentary on CBC's Marketplace about this popular chicken jerky treat which I've always bought at Costco; thousands of dogs are dying all over... including my last one... of sudden kidney disease because of these treats, and its been going on for years.
There is something in the glycerin. Check out their Facebook page to see what others say, and also the CBC's website on this documentary which, I understand is also going to air through the US on Saturday 29 September.
These and other treats made in China, should be avoided at all cost. And the packaging, as do many dog treats, fool you into THINKING they're made in your own country. Canada, doesn't even have regulation for dog food.
Love, your dog? Spread the word.
