Which is the strongest sense of the dog?

Many people think that the sense of smell is the strongest sense of a dog. However, dogs also have a number of other senses that are at least as strong. In fact, it is possible that some of these other senses are even stronger than the sense of smell.

A dog has about 220 million olfactory receptors in its nose – an impressive number. But it also has about 18 million color receptors in its eyes and more than 60,000 hair cells in each ear. So these senses should not be underestimated.

Although the sense of smell is the best-studied of the dog’s senses, there is evidence that its other senses are at least as strong. For example, dogs can perceive sounds that are inaudible to us humans. They can also perceive the smallest movements and remember images they saw long ago.

All these senses together allow the dog to perceive a world far more intense than our own. Image by wirestock on Freepik
