Why a mongrel will always trump the pedigree chump (2008)
Journal Article
Smith, D. (2008). Why a mongrel will always trump the pedigree chump. The Mail,

With a pedigree as long as his tail, you might expect the pure-bred pooch to trounce his mongrel cousin in an IQ test.

But it seems that all that breeding may be for nothing. For when it comes to intelligence, scientists say the crossbreed wins, p... Read More about Why a mongrel will always trump the pedigree chump.

Smith, D. (2006). Episode 30 - Dog intelligence

Are you a fan of pedigrees or do you prefer crossbreeds? Opinions on this area can be very heartfelt, and the issue is clouded in myth. Which is more intelligent though, a pure pedigree or a mixed up mutt?

At Aberdeen University in Scotland, Dr D... Read More about Episode 30 - Dog intelligence..
