This article is from the Afghan Hound Breed FAQ, by Janis Nixon with numerous contributions by others.
As Afghans are more of a tall, streamlined type of dog, they eat far
less than their size would imply. Afghans need a high quality dry dog
food, with plenty of vegetable oil to keep looking and feeling their
best. It is also necessary to protect those long ear fringes with
snoods. These stocking-tube type hats hold the ears back from the dish
and the fastidious Afghan doesn't soil his hair.
