Trivia: The largest section of a dog’s brain is responsible for what sense?
Sight
Smell
Taste
Hearing
The correct answer is Smell
So why is this answer correct? : A dog’s olfactory cortex makes up one-eighth of its brain. Dogs can have more than 100 million scent receptors, and breeds that are known for their strong sense of smell, such as bloodhounds, have up to 300 million scent receptors. This allows them to detect complexity in odors, such as specific ingredients in food and even signs of health issues. Research has found, for example, that dogs can be trained to sniff organic compounds associated with different types of cancer.
