A vegetarian dog? letters.

RE your feature on the vegetarian dogs: A vegetarian dog - surely not! Man is omnivorous but dogs are carnivores - they eat meat.

Over thousands of years we have encouraged them to adapt their diet, to a eat a certain amount of grain-based food - dog biscuits and the like but that has undoubtedly led to the fact that they now produce a much greater amount of faeces than would be the case if they were fed that which their bodies demand - a high-protein diet.
