A raw diet provides a range of benefits that commercial dog diets can never hope to even closely match.
These benefits include:
no doggy odour
naturally cleans teeth - no need for toothbrushes, de-scaling jobs, or gum disease
the time it takes for a dog to chew a raw meaty bones give their stomach adequate time to get the acids moving
much less stools produced - and they are firm, and turn chalky after a couple of days
decreased or non-existant vet bills (your dogs are healthier!)
less cost for dog food - commercial dog foods are ludicriously expensive
mirrors what a dog would be getting in the wild - and certainly even the modern day dog has a digestive tract exactly the same as a wolf
puppies develop at a more appropriate rate - and quick growth spurts are avoided. A GOOD breeder will want to stop fast growth in any pup.
the ripping and chewing involved in eating raw meaty bones develops the jaw, neck, and shoulder muscles of the dog. Commercial dog foods will never assist in this important muscle development.
