Hi mate, depending if you have a decent local butcher, if you have ask him for any meat trimings, bones, etc. If not, Netto have a special offer on at the moment. They are selling a food called Worker, it is brilliant. I feed my house dogs and when I get short of food, I feed my yard dogs it. Brilliant. BEWARE, if you feed too much flesh, it is hard to get your dogs down to a decent weight quickly. I hope this helps, it is all trial and error. No one taught me.
