These chicken strips (and most others like them) are priced so low they are hard to resist. My dogs love them of course and for dogs who tolerate chicken, they should be excellent treats. However, I do not trust pet foods sourced from China. Most of you should remember the melamine disaster of several years ago that killed and permanantly injured over ten thousand pets. It remains almost impossible to determine the conditions under which chinese food products are produced and manufactured. The rumors in the veterinary world (I am a DVM)are that the majority of the chickens used in these cheap products are dead before processing. No one has any clue what, if any, adulterants are added. Many brands are irradiated (if this matters to you). Overall, I recommend purchasing pet food products that the manufacturer guarantees are made 100% from US grown and processed ingredients.
