 I switched my dogs to the Lucy's Pet Formula several years ago. Both my puppy that I rescued five years ago, she's in the car next to me if you hear her whining. Oh, I can hear her okay. And my senior dog, both were on that, and they love it. I do the Duck and Quinoa Lucy Pet Formula. I love when I get calls like that because that's what I hear every day. Once people have made the change to Lucy Pet Formula, it's like pet food for their dog or cat.
