Dude, don't take it personally. We're just debating the "EVO is the best food for your Pit Bull" mantra. All dogs have different nutritional requirements. Just because you feed the most expensive brand on the shelf, that doesn't mean that its going to be the best food for every dog.
Yes, you want to feed your dog the best food you can get. But if you're dumping a lot of nutrients into them that they don't need, I'd think it could be counterproductive. I wouldn't feed Evo to a puppy. The folks I know who feed food like that are conditioning their dogs for the ADBA show ring, which means working them hard so they really need the extra protien. Any decent dog food is going to produce less poop than your standard grocery store junk.
