A really cheap way of feeding is on chicken carcusses, although you do need to find a supplier first, we get a box for £5, and there is loads of meat on them, this feeds my six dogs for 3 days (3 BC's, 2 GSD'S and a GSD X BC). The other days in the week they have Burns complete food. I know lots of people say you shouldn't mix food in this way. All my dogs are fit and healthy and live to a good age, remaining fit up to the end, so I am happy with it. They also never have stomach upsets.
