I just found a piece of Plastic poking out of a piece of Callies dog food when I was feeding her this morning

I have been feeding her Natures Variety Instinct Chicken meal. I will being emailing the company right after I eat breakfast. I really hope there weren't any in what she has eaten in the last week! I am gonna see if she will eat the Taste of The Wild that I have if not its on to find a new food. Just wanting to let everyone know in case you feed this food.
