...Your friend needs to do some serious research in RAW feeding. Kibble leaves behind tartar-causing agents, because the
dog's system is not designed to digest the stuff that's in it. Yes, the Raw diet should consist of mostly muscle meat and a percentage of BONE and organs. Poor Greyhounds, if they only got soft meat while working. And, doesn't that tell one something? That the owners knew their dogs would fare better on raw meat (be stronger for the races), so fed them accordingly for performance! My dogs - one Yorkie (23months), and one mix (in his 13thyear) never have stinky breathe. The vet can't get over how great their teeth are. I never have them cleaned
