Hi Michelle, I feel the same way about my guys. I feel they don't always seem to drink enough water, they have all day access to a pet water cooler, and I always add water to their meals. They will drink when they have come back from a longer walk, or if they've been playing hard. We feed our guys Fromm's Lamb and Lentil, so I'm not familiar with raw or wet food. I'm not sure if they need less water if fed this way, but I tagged Ftse (Julie) for you, as she feeds her bullies a raw diet and maybe she or someone else with more experience with raw feeding can answer your question. I think as long as he has access to fresh water and you are adding it this food, I think he will drink what he needs.
