You can go to
www.dogfoodanalysis.com to review different dog foods. I'm not sure they put puppy food on there, but they might.
It does seem like new people come on here and say the breeders are feeding Eukanuba. I've seen it a few times. Weird.
Anywho, I wouldn't feed Eukanuba to mine, but that's a personal preference after I did research and came to my own conclusions. I urge you to do the same just so you know what you're feeding your pup. Just like you would look at the nutrition label of your own food, you should do it for your pets.
Good luck!
