I'm sorry but anyone that believes that raw diets are bad, is very uneducated or manipulated by dog food companies.
Most health problems in pets are caused by dry kibble. My cat is dying of hyperthyroidism as we speak caused by cat food. I will not let this happen to the rest of my babies. 1 day ago RAW BONES ESPECIALLY CHICKEN DO NOT CHOKE DOGS! They are soft and very good for them. Only cooked bones harden and splinter. I've been feeding raw for a couple of years now, you definitely need to do your research first.
that said, I only buy some of my food at the grocery store. I buy my veggies there, I put them thru the food processor, mix with pumpkin and freeze in large yogurt containers. I also buy yogurt, plain, in large containers, eggs (I give 1perdogperweek), canned fish (salmon, mackerel, sardines, what ever is cheapest), also bananas and apples. I keep an eye out for deals on meat, I usually feed chicken, yes, bone and all, but I have found some meat shops that now do meat for raw feeders, you can buy the carcas of a chicken, or get them ground, I buy by the case and freeze. I will by gound beef when on sale, and package up for daily use. Raw feeders should get organ meat 2 or 3 times a week, so I watch for deals here too, have found I can get turkey hearts at one of the farmers markets I go to so I buy in bulk and again freeze in baggies for the amount I need. Periodically I will pick up a kidney, beef heart or tongue. It sounds like a lot of work, but once you get the hang of it it isn't. A good freezer is essential. You can buy commerically prepared raw, fine if you only have one small dog, but as I have more and they are larger I do it myself.
always use human grade meat. Beef bones are too hard to be part of the meals, but I use beef ribs for their recreational bones, they love them and you don't run the risk of getting a knuckle bone caught on the jaws.
For special treats I will feed ox tail or turkey necks. You will find that dogs love it.
I do use vitamin supplements- which I did when I fed kibble, vit C & E (antioxidants for cancer prevention), kelp (good for pigment, I have show dogs, and iodine for thyroid health).
good luck, but again, do your research first
