Hi Sherry, I've found it depends on your local costco which Kirkland brands they carry; almost all carry chicken & rice & lamb & rice, not all carry the puppy chicken formula. I think I last paid $26 for 40 lb bags of chicken & rice. The formulation is exactly the same as Chicken Soup for the Dog Lover's etc., etc. that you find in the super premium stores for a whole lot more $$$$$. I've been using it for 10 years...and before that I used Pro Plan for 13 years...very VERY pleased w/ Kirkland.
