My dogs did fine on it for a few years. Well until all that crap with the menu-foods recall. There was malomime in the rice-protein concentrate, or corn-gluten. At that time, there was a lot of recalls on a lot of foods. Several of my dogs did get sick.
I think it is hands down better than Beneful, so Kudos to your vet for getting you to switch.
I also think there are better foods for the money. I was shocked at how much Nutro was charging recently. Their food is a middle of the road type of food, not terrible, not premium. I think if you are paying much more than $1/pound for the ingredients in that stuff, your are getting rooked.
The thing is, if you go to a more premium food, the chances are you will feed less and make up the difference, and not even pay more even though a bag of the better food will cost more money.
I went from Nutro to Canidae, and it was true that by feeding less of the better food, I actually paid less. And my dogs did well on the new food. Until they had a problem, switched manufacturers, and changed their formula.
