Sheepjoke, I am really very lucky to have a great supplier nearby me (30 minutes away, a gorgeous drive through the country).
I pay .98 a lb for coarse-ground beef, 40% fat. Their organ meat mix is $1.15 a lb, I think, (heart, liver, kidney, tripe). Occasionally I buy straight ground tripe, but it's a little pricey at $1.55/lb.
I also buy the bones from them, .55 a lb. Between the 3 big girls I have been spending about $125/$150 per month feeding them, total. This includes the supplements I buy for them. I expect my bill to increase by $30 or so a month as the 2 puppies grow up and start eating more.
Not cheap, but not that bad either. I do buy some chicken at Walmart, they sell leg quarters for .48/lb. I always have several 10lb bags of that on hand. I buy other stuff for variety as it is on sale such as chicken backs, beef kidney, lamb or rabbit every now and then.
I have been a raw feeder for a long time, and altho this is a lot of money to feed dogs, I accept that expense. I always get comments about the coat and condition on my dogs, and you should see their mouths.
I also have an old gal who will be 11 in mid March who is still doing very well. If not for her one bum hip, you would take her for a dog 4-5 years younger than that.
