Meat can be raw or cooked for pups, but remember that dogs need more than just meat. ... Pups digest meat more easily when it is minced but by the time they are three months old they should be getting pieces big enough to chew. Some raw meat puts your dog at risk for salmonella, a bacterial contamination.... Raw meat is not recommended for puppies, dogs with liver or kidney failure, or dogs with cancer.
Between four to six months of age, the permanent teeth appear and grow rapidly. Introducing fresh raw meaty bones at around 12 weeks of age ensures they are chewing actively around the time the permanent teeth erupt.
