Every dog lover has witnessed it: that moment when your sleeping dog begins to yip or move his legs as if running or even growls at imaginary foes.
Turns out that researchers think that, like humans, when a dog dreams he’s replaying the day’s activities.
Pets go through the same multiple stages of sleep that humans do, from periods of slow wave sleep to REM (rapid eye movement), where most dreaming occurs. What differs is the frequency of the dreams. People cycle through REM sleep every 90 minutes, cats every 25. In dogs, that cycle depends on the size of the dog. Smaller dogs enter REM sleep more frequently than larger dogs, but each episode is much shorter.
So the next time my dogs Bandit and Scout start yipping in their sleep, I’ll assume they’re enjoying another rousing round of water dog or fetch!
What do you think your dog dreams about? And what’s the funniest thing he’s done while sleeping?
You can read more about dog’s dreams in an article on the HealthDay website.
