Abstract
ALTHOUGH under natural conditions largely carnivorous in its dietary requirements, the domesticated dog will accept with apparent relish a diet more fitted for an omnivorous or even vegetarian animal. Flesh, milk, cereals and vegetables make up the bulk of the ration, the proportions of these varying according to the fancy or perhaps the financial circumstances of the owner. Thus the amount of vitamin A available to the dog will vary greatly.
