Do Dogs Really Dream?
Do Dogs Dream?
Dogs dream like humans and about similar things. Many people believe that dogs do dream. Most dog owners have noticed that at various times during their sleep, some dogs may quiver, make leg twitches, or may even growl or snap at some sleep-created phantom, giving the impression that they are dreaming about something.
Scientists think so—in fact, they believe that dogs not only dream as we do, but also that they dream similarly to us, meaning that they replay moments from their day while they’re fast asleep.
How do we know that dogs dream?
Back in 2001, Researchers at MIT trained rats to run a maze and measured their brain activity. Later they measured the brain activity while they were in rapid-eye movement sleep, the sleep cycle in which humans experience dreams. They found that the brain activity was the same as when the rats were running, leading researchers to conclude that the rats were dreaming about the maze they ran earlier that day.
“No one knew for certain that animals dreamed the way we do, which can involve replaying events or at least components of events that occurred while we were awake,” said Matthew Wilson of MIT’s Center for Learning and Memory. “We looked at the firing patterns of a collection of individual cells to determine the content of rats’ dreams. We know that they are in fact dreaming and their dreams are connected to actual experiences.”
Because rats are intellectually less complex than dogs and cats, researchers make the assumption dogs and cats dream just as rats do.
How do we know that a dog is dreaming?
Dogs often bark or twitch their legs during REM sleep, the Sleep Foundation reports. But sometimes, watching a dog dream can be indicative of his breed. “Researchers found that a dreaming Pointer may immediately start searching for game and may even go on point, a sleeping Springer Spaniel may flush an imaginary bird in his dreams,” AKC Family Dog columnist Stanley Coren explained in Psychology Today. Coren also advises that owners who are curious to know if their dogs are dreaming to simply watch them beginning about 10 to 20 minutes after they fall asleep. If you can see their eyes moving behind their eyelids, they’ve begun to dream.
What To Do If Your Dog is Dreaming?
If you notice your dog having a dream, follow the old adage “let sleeping dogs lie.” Disrupting his sleep during the REM cycle can be startling (think about how you feel waking up from a dream), which can result in an unintended bite or, at the very least, a sleepy dog in the morning.
