I heard from a GSD owner I know and other owners with different breeds do the raw diet thing and they say it's more healthier than kibble. When I asked a friend what do you look for in a breeder, she answered "you want to make sure they have raw diet only." The raw diet is said that dogs live longer than those who eat kibble which shortens dogs lifespan. What is true? I'm in a big confusion about raw diet and kibble and which is better. Is there only 1 answer like raw diet people say?
