I've also read that some dogs eating chicken jerky will not eat their regular food. Somehow they get addicted to the chicken jerky, perhaps something in there that's addicting...So the owner continues to feed the chicken jerky & they can also get sick from lacking vital vitamins & nutrition from not eating their regular food (unbalanced diet).
IDk if VitaLife (which is made in Thailand) made that dog sick & ultimately cause his death, but they made an official response that VitaLife chicken jerkies were tested & approved safe.
