Avoid this product on Amazon
Flavor Name: Chicken & Sweet Potato, Size: 10.5 Ounce (Pack of 1)
I will never buy this product off Amazon again. My dog who recently passed got sick on this product when I bought it from Amazon, I thought I'd try it with a different dog, same awful results and I'm just out money. If your dog likes these I recommend Chewy. And Amazon doesn't refund food 😡 maybe they are waiting for someone to sue them or die before they change that policy!!
