Oh! And, speaking of
'by-products': since raw meat, bone and organs are more easily digested, the dog gets more complete nutrition and fuel from his diet - LESS WASTE!
What comes out is much less in ratio to what went in
, and it's nothing like the poo of kibble-fed pooches. Prey model diets generate less waste, and it dries to a white lump, that crumbles to a chalk-like biodegradeable powder. Unlike the poop of kibble-fed pooches that is gooey and sits forever, preserved by all the non-degradeable materials in the dog 'food'.
