No, there is no evidence to support this claim. In fact, many studies have shown that raw meat diets can actually reduce aggression in dogs. It is important to note, however, that all dogs are different and some may react differently to raw meat. If you are concerned about feeding your rottweiler raw meat, it is always best to talk to your veterinarian first.
