Dogs vs. Humans: A Showdown of the Senses

Dogs vs. Humans: A Showdown of the Senses — page 1 — DOGS can do some incredible things like find hikers lost deep in the woods or spot intruders sneaking around in the dark How do they do it They use their keen senses Long ago before they became the pets we know today dogs were wolves And their senses had developed in ways that helped them survive in the wild For example they used their senses to protect themselves from danger search for food and water and find their way home That past still shapes the way dogs experience the world today Only now they mostly use their senses for more fun activities like spotting squirrels waaay across the park and hunting down unattended hamburgers When a dog’s senses detect something such as that delicious hamburger they send messages to her brain Then her brain tells her body what to do in response to the information That burger on the picnic table looks and smells like it’s going to taste really good Go for it FIDO FACT Dogs evolved from wolves at least 15,000 years ago
