<!-- Domestic dogs often display the remnants of counter-shading, a common natural camouflage pattern. The general theory of countershading is that an animal that is lit from above will appear lighter on its upper half and darker on its lower half where it will usually be in its own shade.<ref name="About.com">{{цитирана веб страница|url=http://animals.about.com/od/zoology12/f/countershading.htm|title=What is Counter Shading?|last= Klappenbach|first=Laura|year=2008|publisher=About.com|language=English|accessdate=2008-10-22}}</ref><ref name="Encyclopedia of Dog Breeds">{{цитирана книга|last=Cunliffe|first=Juliette|title=The Encyclopedia of Dog Breeds|publisher=Paragon Publishing|year=2004|pages=20–23|chapter=Coat Types, Colours and Markings|language=English}}</ref> This is a pattern that predators can learn to watch for.
