I totally agree Science Diet is seriously overpriced crap (unless you have the prescription foods for a diagnosed condition, that stuff is usually ok). I do NOT understand how they get away with charging what they do for what they give you. I remember people saying it's hard to find good food for any pet in Australia. The import restrictions make it difficult and expensive. You want at LEAST the first 2 ingredients to be meat meal or meat, so like chicken meal, beef, lamb, etc, first 3 is even better. You know, stuff you can pronounce and not be repulsed by. Dogs are much more omnivorous than cats, they have flat grinding teeth too, but definitely see if you can get him on something healthier. You'll be glad down the road. I can ask someone from another board if you're interested in a recommendation.
