Hi Zach –
Primal’s raw formulas could certainly be used as a topper to boost the quality of kibble. You could also use tinned sardines and fresh veggies. The benefits of using the Primal would be that it’s a complete and balanced food so you could add as much as you wanted and it’s raw however, canned sardines and fresh cooked veggies would still be a good boost and would certainly be cheaper. If you go with the Primal, like I said, you can add as much as you want because it’s complete and balanced – just be sure the reduce the amount of kibble he’s receiving accordingly. If you’re feeding sardines and veggies, it should account for no more than 10% of your dog’s calories.
