you people are 'way overthinking this. i've been feeding raw for five years now, and my pup's breeder has been feeding raw for more than a decade, at least.
i started out like y'all are: worried about bones, worried about ratios, making up recipes, scheduling what is eaten on what day.
it's all a complete waste of time and energy.
feeding raw is easy, simple, and cheap, once you get over the initial hump of learning how to do it and, perhaps the biggest challenge, finding good providers of rmbs.
you don't need to have certain foods on certain days. you don't have to feed tripe. you don't have to feed veggies with meats or a certain number of days of the week.
and you certainly do not need to grind bones, not even for puppies that are weaning. in fact, it is correct, cutting or chopping the bones makes them dangerous. let the dog deal with the bones. just make sure they are raw (this means you didn't defrost them in the microwave, either).
and wolves, btw, DO eat every last scrap of a deer in the wild. i know, because i've spent time tracking them in the wild with wolf biologists. when you get to a kill site, there is NOTHING left but maybe a hair or two, and the blood on the snow. it's rather amazing.
the first thing you must do when beginning raw feeding is find out what meats are available in your area. you call every supermarket and every butcher and every meat processor in the county, and ask them what they can get you for under .99 cents/lb. you explain that you want HUMAN GRADE, non-weight bearing meaty bones: tails, necks, ribs, heads, wings. you also want organ meats: kidneys, hearts, livers. and you want these things from as many different kinds of animals as possible: turkeys, cows, pigs, chickens, lambs, rabbits, deer, elk, moose, etc. (do not feed bear or lion--trichinosis).
when you've figured out who your best provider is, order what you need by the case lot, and have the butcher cut or package everything into one-meal sizes. for example, for my mastiff, the butcher packages beef hearts as half a heart to a package, three turkey necks to a package.
chickens i feed whole or half. young fryers are usually cheap from the supermarket.
ok, put in your order, toss the stuff in the freezer, and you're done with shopping. you take out a week's worth of stuff at a time, and let it defrost in your fridge. if you forget to defrost, or run out--feed it frozen! no problem.
as for a schedule, mix it up is the only rule. if he got beef heart and half a chicken yesterday, today he'll get turkey necks and a can of mackerel. i try to once a week feed ground up veggies mixed with egg and shell and yogurt or cottage cheese and some fish oil and kelp, but as long as he's getting organ meats, the veggies aren't essential. sometimes if i'm short of meat, he'll get a bowl of cottage cheese and an egg with the shell.
i save the trimmings from the veggies we eat, and when there is enough saved to make a meal for him, then he gets a veggie meal. simple.
you can get impaction from feeding too much bone. the remedy for that is to feed more meat and/or organs. watch his stools. if they start getting too hard or he's straining, up the amount of meat, veggies, organs. if they are getting a little runny, up the bone.
same thing with how much to feed--if he looks skinny, feed more. if he's plumping up, feed less.
and worry a lot less!
