This article is from the Afghan Hound Breed FAQ, by Janis Nixon with numerous contributions by others.
In general, Afghans are a quirky and unusual breed, but there is one
part of the Afghan's nature that is often overlooked. Afghan Hounds
are thieves at heart and will filch anything that takes their fancy.
They can be quite innovative at getting into areas their owners want
to keep them out of, and their ability to whisk food or articles away
from right under the owner's nose is almost magical. The intelligent
owner must child-proof his home thoroughly and keep one step ahead of
this furry Houdini.
When an Afghan finds himself in a stressful situation, quite often he
will simply go to sleep until the whole business is over. Another sure
sign of an excited or worried dog is a drippy nose.
It is almost impossible to keep an Afghan off the upholstered
furniture. They seem to think that this is their rightful place. They
have been known to push their owners out of bed. To the true Afghan
fancier there is no substitute for this gentle, entertaining,
frustrating and most kingly of dogs.
