Hi, I'm in the process right now of switching both my dogs from Kirkland to PC Nutrition First. One dog is 1.5 years and his little sister is 5.5 mos. They did ok on Kirkland but they always had the runs so after alot of research on different brands, comparing lables I went with the PC.
SO FAR SO GOOD, and I won't have to make the 1/2 hr drive to Costco every month
* Happy feeding. *
