Kibble or pellet food is not an appropriate diet for any dog, says US animal nutrition expert Dr Richard Patton.
Patton says there are benefits to matching an animal's diet to its genetic machinery.

He encourages pet-owners to make their own pet food using vegetables and meats.
Alternatively, he says they should buy products from local companies that specialise in raw food diets for animals.
