the ideal raw diet is that dogs eat as they would in the wild... and there are no food grinders in the forest, LOL
so yes, feeding intact and whole pieces is the best way to go... check out

the ideal thing with making raw mixes (for us) is that we can add raw organ meats (which neither dog will touch with a 10 foot pole!), raw fish, blend in some raw eggs, baby food, etc - and dump it down the dog's throat and voila, we are sure that the daily quota for perfect nutrition has been eaten.
BUT you could do the same with a few "mush meals" per week (ground raw meat of any kind + mix in "stuff") since your boy eats enough bones on his own to balance things out
If dakotah was food-motivated (he never was) and liked to eat enough food every day to sustain his 120 lbs frame, then we would not grind anything and save ourselves 3 hours every 3 weeks or so
I say don't grind anything, keep feeding whole meaty pieces with proper bone ratio, vary the protein sources and consider adding treats such as steamed veggies if your boy likes them, feed the occasional "mushy meal" with goodies mixed in (pasta is always a hit here!), like baked sweet potatoes, raw eggs, canned fish, don't forget the organ meats, anything you see fit to feed, in fact!
i hope this is encouraging!
