So, I started Ringo on the NV raw medallions (lamb) last Saturday and he LOVES them! I have never seen him so excited about his food. When he first came home with us I was feeding him Purina Puppy Chow (what the breeder had been feeding), then switched to Iams Small Breed Puppy on the vet's recommendation, and then switched again to Wellness puppy after reading up on good quality food. He handled the changes well, but was never really excited about mealtime and would sometimes pick at his food or just ignore it. But with the NV, it doesn't sit in the bowl for 5 minutes before he completely scarfs it down. I'm so happy I tried this! I feel like I finally found something he really likes AND is really good for him!
Thanks again to all YTalkers for your advice!
