I've done a lot of research before getting my puppy 2 years ago. Don't want to start a debate and go too much into details but just think about it. Dogs are descendants of wolves and share 99% of their anatomy, even if they have been domesticated for centuries. Wolves are scavengers of the wild and no animal cook/process their food.
Anyways my dog is in a raw diet since 2 months old and she just turned 2 today. Perfect health, soft fur, pearl white teeth. Her food costs $25/month at your local asian supermarket and 5min to prep.
If she wasn't on raw, I'd go for Purina Pro Plan based on what I've read.
