Hi Sue
If you feed a raw (I refuse to use the other word) diet it should consist of meat, bones, organ meat,fruit and veg, fish plus any supplements that you choose to use such as cottage cheese, yoghurt, linseed oil (obtainable from horse feed outlets), kelp or seaweed power.
On the bone side of it I feed primarily chicken but also add lamb breasts, rabbit when available, fish, turkey, duck, pork and lamb necks.
Imagine a boned chicken with no legs, wings, innards and the breasts removed. If you chop this in half, back and front you are left with frame/carcass which has the ribs on it and the back which is what would be the back of the chicken, tail and where the legs join.
You do not need a mixer if following a totally raw diet. There are various books available and they all give slightly different advice (of course) along with the many web sites that deal with raw feeding.
The site you mention may be the Billinghurst based one? This is based in the US and, in my opinion, seems to go to extremes.
I have found the cost to be slightly under what their food was costing me before and I did not use a premium food.

Hi Sue,
If you do a Search under my name you will find links to sites that I posted for someone recently. I changed around Sept and my dogs love me for it. It really isn't as hard as it first seems. This is a good site for asking questions, owned by a vet who raw feeds
HereLots of very down to earth people who like to be asked questions. If you want to ask questions feel free to email me privately but I'm no great expert, just near enough starting to remember how scary it can be
