Mine get meat with bones. I dont usually grind up theirs because, well its time consuming and they hoover everything anyways.
typical shopping list for me...
Chicken legs with backs attached
bone in lamb cubes
liver
fish
hamburg
ground pork
and I have gone to the pet store once and got pre ground chicken with bone in it.
Typical meal
a few chicken legs with backs
chopped liver
canned salmon ( not tuna right TD
)
blended veggies ( they dont even notice it at all)
and hamburg.
some days they get lamb, rabbit, beaver
moose, deer just what ever we have frozen for them.
And for recreational chewing ( and to keep them occupied outside) they get RMB's
