My last Lab (14 year awesome run) consumed nothing but dry Pro Plan her whole life. The breeder used it and I never changed. I started my current Lab on Authority (Pet Smart) which according to my vet is rebranded PP and what he uses. The labels confirm this with the Authority having a couple of extra ingredients, Omega 3/6 and Glucosimine. I didn't like the way her poop looked (mebbe too "rich"), so I have almost completed the transition over to Pro Plan and I think it suits her better. She's almost two now fwiw ...
You might have to adjust the amount down if your pup isn't "very active" though.
