Why do greyhounds have to touch what they are smelling with their noses? I realize that they are sighthounds, but that does not diminish their incredible sense of smell. They sniff and snark my clothes when I come home. They snark and sniff strange items and other dogs. I have even seen them touch their noses to a pile of poop they are smelling.... YUCK! What is up with that? Can't they smell it from an inch away?
