Starting your puppy on a species-appropriate diet is the best thing for proper skeletal and muscular development. Puppies can start on a raw diet as early as four weeks. We suggest starting them off with a simple protein source, like Pure Turkey or Pure Rabbit, for 5 to 7 days as these are easily digestible proteins and allows them to adjust and build a tolerance to their new raw diet. If there are no signs of digestive upset or sensitivities, you can introduce your puppy to other protein sources.We suggest adding and rotating a few great supplements to boost their immune system, like Goats Milk & Bone Broth.Raw meaty bones, chicken necks, and turkey necks are also a great addition to your puppy's diet and meal supplementation a few times a week. It is important to always supervise your dog when they are enjoying a raw bone, and always get a bone that is larger than their mouth to avoid swallowing hazards. Especially until you learn how your dog chews and which bones may be suitable for them.
