We recently got Thunder from his breeder, who was feeding him Purina. After reading reviews online and scrolling through different threads on this forum, it feels like I need to make a switch. He just turned 9 weeks, and he hasn't had any diarrhea or any trouble eating, he weighs a healthy 20.7 lbs. Should I wait a few more weeks incase the switch upsets his stomach this early of an age, and which food would you recommend? I'm in Canada and the only pet stores in my area where I live would be Petsmart, Petvalu, and Global Pet Foods. Below is what he has been currently eating from the breeder. Looking for any suggestions!
