The Cost of Feeding a Raw Diet

At Klancraig we 'raw feed' our dogs - that is to say we feed them a species appropriate diet of raw meaty bones, minces, offal, fish, eggs, fruit and veggies. (A more detailed description of how we feed our dogs can be found on our website, on the Dog Care page).
We are members of several forums dedicated to this subject and recently, on one of those forums the subject came up relating to the cost of feeding a raw diet. Obviously, cost will be dependant upon the size of the dog, how much he or she eats and how varied the raw diet is that is being fed. It has been sometime since I actually sat down and calculated this but given that we do feed a very varied diet to our dogs, I was pleasantly suprised to find that it costs approximately 70-80p per day, per dog according to what we actually feed.
