Researching how dog noses develop
Dogs have a huge olfactory lobe that helps them process all of the scent-related information that they take in. The size and complexity of this structure in the brain is one reason that dogs have such an amazing sense of smell and can detect bombs, cancer, drugs, lost people and even the tiniest trace of dog treats that I’ve accidentally left in my work bag. The dog brain is only one part of the anatomy responsible for their extraordinary sniffing abilities. The canine nose also contains key features that contribute to dogs’ superior skill at smelling, but only recently have people studied how the structures in the nose develop.
