Here's why:
* Evolutionary reasons: Dogs are descended from wolves, and wolves are active predators that need to conserve energy. Sleeping allows them to rest and be ready for their next hunt.
* Age: Puppies need even more sleep than adult dogs, up to 20 hours per day. Senior dogs also tend to sleep more.
* Breed: Smaller breeds typically sleep more than larger breeds.
* Activity level: Dogs that are more active during the day will need more sleep.
* Health: Illnesses or medical conditions can also lead to an increase in sleep.
So next time someone tells you dogs sleep less than humans, you can confidently correct them! 🐶😴
