Cons
- Does not meet WSAVA guidelines as rigorously as Purina, Hill's, or Royal Canin

Our take
Blue Buffalo hits the sweet spot between quality and cost. It's not as scientifically rigorous as Purina Pro Plan or Hill's, but for owners who want better-than-supermarket ingredients without a subscription or premium price, it's a solid pick.
If your vet hasn't already told you to try Purina Pro Plan, they probably will. It's the brand Reddit's dog food community and veterinarians keep circling back to — for good reason.
