I'm in the same raw food coop as Scornning (wazzuor.com). I get a bunch of stuff there, but probably 50% of Denna's diet comes from human shops - Pork Shoulder and Ribs from Costco, Cash & Carry and/or Restaurant Depot (my BIL is a professional chef), and Fish, Liver, Kidney, Heart, Beef Feet and other parts as available from H-Mart (big Asian Grocery).
I've been averaging $2.50/lb for over 5 years now. I can get a lot of the boneless meat for under $2/lb, even at Costco, and lamb ribs from the coop used to be under $2/lb also (but have been increasing lately). Fish (whole frozen mackerel) is about the same price in the coop as at H-Mart; around $2.50/lb. "parts" - pork or beef - liver, kidney and heart - can be more expensive, but they're a much smaller portion of the diet.
The average cost goes up when I add in variety with Venison or Bison, and goes down when I add Chicken - which I haven't done a lot of, due to potential allergy/sensitivity issues... which I no longer blame on chicken, but just haven't tested it much.
Denna is a very low-energy 160lb EM... she eats 1.75lb/day. She used to get 2-2.5lb/day, but tore her CCL, and gained a bit of padding during her rehab. She's all better now, and back at her trim weight, but we still haven't returned to quite the same level of weekly activity (which isn't good for my waistline, either, and I don't have anyone watching MY portion sizes, unfortunately).
I go by Whole Prey Model Raw: 80/10/5/5 and also add in veggies (not included in meal weights), about 25% of one meal only, so 12.5% of the diet... the veggies help regulate (increase) poop size for Denna... otherwise her anal glands bother her and she starts scooting around the yard.
I feed her in her normal raised dish, same as when she got kibble (we transitioned to raw when she was about 6 or 7 months old).
I do have a plastic carpet protector under and in front of her dish, so when she drops larger bone-in parts on the floor, it's on a plastic "place-mat"... and she licks it very clean before she "leaves the table" so to speak.
It took maybe 3 reminders for Denna to keep her food either in the dish or on the plastic, she never tried to take stuff to her rug for chewing on. If she gets a big knuckle bone or other "recreational" bone, those she gets outside... I've had to go un-bury a few to keep the local wildlife from wanting to invade our yard...
I'll add that I believe in the value of fresh, whole foods... for the humans, canines and felines in the house... while kibble may be convenient and perfectly healthy, adding some fresh food in on top or randomly as "treat days" can only help... in my opinion. So, if you decide raw isn't for you, I'd still recommend tossing your pup a raw meaty bone every once and a while, or giving them meat scraps (or veggies, if you dog likes that) from your human meal prep, or even some freshly cooked foods (before you spice them up too much) from your own meals. You can do it in ways that won't create a begging monster, too, if you're consistent with the rules....
