We feed raw to our pack -
They get a mixture of pheasant, rabbit, hare, partridge, fish, venison, lamb/mutton, beef, chicken, duck etc etc a long with some eggs, veg, cod liver oil and other bits and bobs. Mostly fed as whole carcasses, often with skins, although the birds are plucked, to avoid mess in the kennels / yard.
Someone mentioned freezing food - this is good advice, especially when feeding certain animals, such as rabbits etc. Although I worm my dogs regularly, at the rate that they eat carcasses, they would still carry a worm burden, freezing the carcass for a couple of days, kills many of the worms and other parasites.
We feed raw for a number of reasons, mainly due to the noticable improvement in the condition of the dogs and the cost (raw costs us nothing, but a good complete for seven working dogs costs a bomb!).
