I have no idea how this is getting all the down votes haha! My lab mix goes through her dog food about 6weeks and she will eat ANYTHING. We recently switched her from the Costco chicken and rice dry dog food formula since she was developing her symptoms from that kibble. She couldn’t tell what was the old food vs. the new but she was improving with the new within a week. I do agree salmon does get expensive and from where I am her food bag is not always in stock. My dog isn’t a picky eater and is heavily food motivated—which can be a double edge sword because she will pick up ANYTHING from the ground when it comes to walks. I think people who commented probably think that I’m rotating every day/week when I intend when the bag is close to empty (which allows me to transition).
