Howdy Folks, It has been 10 years since we owned a dog (also a Sheltie) and there have been a lot of new foods introduced over the years. We want to make sure that we feed our 5 month old the absolute best possible dog food we can buy. Researching food is hard because of all the misinformation on the internet. However, we came to the conclusion that Wellness Complete Health Puppy food was a good choice. But we're not sure if we're right. Any help with food suggestions would be much appreciated. Thank you for your time. Bill P.
