Lots of people feed raw and dry together here, haven't heard of a single problem before with that, my dogs usually have to go do their buisness after 30-60 minutes after feeding time and its not different with the raw food
But yes, I'll stick to this then.
I'm also trying to get Fido to loose weight, the other one has to gain a little.
I just always weigh the food for them and calculate how much of each they need
