I feed our 6 raw The collies were very hard to feed on kibble/complete dry food as they really did not like it and just didn't eat. I get lamb rib bones/vertebrae parts and chicken wings from the butcher, they get the lamb bones for breakfast and a couple of chicken wings each plus some other bits for dinner. Once a week they get an offal meal liver/kidney/heart, once a week sardines in oil, and twice a week a veggie mix I make up with mainly carrots and Freeflow mince (make 4 big boxes once a month and so get one out each week. Fruit is meant to be beneficial but haven't quite worked out how to add that in yet!
I can't remember what sites to look at off hand, if you google brit barf there is a good forum with helpful people I do have a load of info saved on my computer somewhere about what to feed and amounts for weights of dog will have a look for it if you'd like
In terms of cost MUCH MUCH cheaper for me with 6 dogs, especially as 4 of them used to be on active/working premium complete food and that cost a fortune and to top it off they love it!!
