You can use the feeding calculator on this site to see how much to feed him. Just enter his weight, activity level, and the Calories in a cup of his food. (It should say on the bag.) Make sure to subtract for canned, and look at the Calories for that as well. However, I would definitely not recommend the Pedigree for canned. It is not a quality food. Mixing in canned food is a good idea though, you could look around the review part of the site for some 4 and 5 star canned products to check out. Pure Balance from Walmart is a popular, high-quality canned food that is only $0.25 more per can than the Pedigree.
