Before you start to spend your money on fancy products, Try your local butchers or better still wholesale butchers to see what he does with his left overs(chicken carcass, meaty bones etc...) The lad i get mine off puts them through a mincer and bags them for me. I have found this to be the more favourable and less expensive way of feeding my dogs. Mine also get veg and whole grain brown rice now and again. I supplement there diet with SA37 and cod liver oil. What ever bunnies they catch they are fed those, gutted with there jackets off whole.
