Notice how you have to feed MORE of the Beneful than you would of the Canidae for the same sized dog? Also check the main (first) ingredient. In Canidae it's an actual meat. In Beneful it's corn. What do you think is better for your dog? Have you ever seen a dog grazing in a corn field? Dogs do love meat though.
There are lots of foods out there that are far superior to Beneful. Check this website for some info. and ideas:
