My dogs love these smoked cow ears, and I love it that they are from grass-fed, antibiotic-free cows. I have one large dog and 2 small dogs, I gave these 4 stars b/c they last several days with small dogs. However, my lab can chew one up in a few minutes! The down side, for me, is the cost, the shipping charge is the same as the cost of the product itself, doubling the price. I will order these again if there's a way to bring the shipping cost down.
