Dogs are around us and are part of our family. They give unconditional love and companionship. Is there something far more than what we know about them?

Sense of smell

Dogs have about 40 times more scent receptors than humans. Can smell a single drop of liquid in 20 Olympic-size swimming pools.

We smell and breathe through the same airways within our nose. In dog's nostril, a fold of tissue helps to separate breathing and smelling.

Bloodhounds have such a powerful sense of smell that they can scent trail for 300 hours and follow for 130 miles.

A bloodhound called Nick Carter helped in capturing more than 600 criminals.

Digestive system

Dogs have large teeth to bite, catch, tear, chew and break down food. Adult dogs have around 42 teeth.

Unlike humans, dogs cannot grind food in mouth. They cannot move their jaws in a rounded motion to grind the food.

Dog's digestion process does not start in mouth. It starts in stomach. Because there is no grinding process in the mouth, dogs need to have the food churned and pulped in their stomach.

So, dog's stomach releases a higher concentration of acid to churn and pulp food. If a drop of acid falls on our body, it would burn our skin.

Inside a dog's brain

Even though their brain is smaller than us, they have all the basic structures as we have. Their brain system has equal or greater activation to praise than food.

Language areas of their brain are activated when words not known to them were spoken. Human's language areas are activated when we hear words we know and ignore those gibberish.

Dogs have social cognition. They can infer from the tone of voice and body language, and curious enough to learn new things.

Their brain's reward system was excited by their owner's scent and not by their own or other dogs.

Adaptive skills

Dogs can acquire and retrieve knowledge. They can learn about 250 words.

A border collier called Chaser learnt 1000 words. Chaser could identify objects by their proper-noun name, colour or size.

Sigmund Freud had a Chow-Chow by name Jofi. Jofi would yawn and alert Freud when his allotted time for the patient was over.

Analytical abilities

We cannot expect dogs to do mathematics and analyse complex relationships like us. But, yes, Dogs can do number approximation.

Keep two bowls with food and they can make out which bowl has the larger amount of food.

Emotional intelligence

Dogs are social animals. They learned social behaviour by being in the humans' company for centuries.

Dog's brain functions like human beings. They release the same hormones that humans release during different emotional experiences.

Dogs are good at using the social and behavioural cues than the logical cues.

Spatial navigation

Their inner ear provides constant feedback about their rotations and accelerations for the purpose of path integration.

Dogs may have the ability to use Earth's magnetic field to take shortcuts. They use something called magnetoreception to find their way back home when left out.

Dogs tend to align with the north-to-south axis when they defecate or urinate.


Research into canine intelligence and behaviour is growing. We may get more illuminating facts about our beloved companions as time goes by.

Dogs as mindfulness teachers.

Mindfulness is about living in the moment. There are several benefits of being mindful. Dogs have the inherent traits that help them being mindful.
