My spoos relatives had been fed raw back 5 generations. I switched him to kibble at about a year upon the advice of my vet. My dog got so sick he almost died. He was literally on IV fluids and lost almost 1/3 of his body weight. His breeder said to go back to raw, and he was eating again within a day, and off IV fluids. He soon gained back his weight, and now my vet totally supports raw. That was about 9 years ago. I do not use those expensive raw premixes, but do feed fruits, vegetables, and kefir also. I can't afford all of his meat organic, but do feed totally organic raw organs, like liver, heart, kidney. I think eating chicken leg quarters, bone in, is what kept him from ever chewing on things he shouldn't like shoes, furniture, etc. He has never even chewed up a toy!
Yes, do research raw and other ways of feeding. It is very educational.
