Ive never heard or that one before , not saying your wrong but ive allways known it as bone and raw flesh or bone and raw foods , biologically appropriate dosent make a lot of sense to me , surely dried complete food would class as biologically appropriate ?
Dried food isn't biologically appropriate mate, a dog is a wolf basically which were designed to eat meat and bones not processed bags of wheat and god knows what else they chuck in the mixers at the factory.
