Hm, I imagine stuffing a kong with raw food might be a bit messier for sure. Maybe grinding the raw food up, cut into kibble-sized pieces, then freeze (or possibly even baking would work) to harden them. That might be a bit much as far as work goes.
If you don’t mind the mess and puppy is good at cleaning the kong out completely, just grind up his daily raw meat (leaving the bones out…) and stuffing it in there?
I’d recommend cleaning out the kong regularly, as raw residue could cause some icky build up I’m guessing.
Best wishes with you and your new fur baby!
