Scientific research has suggested that yes, dogs do dream while sleeping and that just like us humans, they mostly dream up imaginary experiences based on their day to day waking life.
Pups often display adorable twitches and woofs while sleeping in their bed, and so youâve probably long assumed they must be having cute doggy dreams.
But unfortunately, our poor canine linguistic skills means weâve never been able to outrightly ask them what theyâre dreaming about or if theyâve even been dreaming at all.
Luckily for us, scientists have gone out and found the answers to our questions. Their evidence for doggy dreaming is incredibly convincing!
How do we know that dogs dream?
Dogs follow a very similar sleeping cycle to humans and go through several stages of sleep while at rest. Rapid Eye Movement sleep, or REM sleep, is the stage in which humans experience the most vivid and memorable dreams, and itâs known that dogs also go through this stage when snoozing. Occurring around 20 minutes into a napping session, REM is the point in a dogâs sleep where actions like twitching, growling and other funny things will occur, the very actions which lead us to believe they are dreaming. And scientific studies on REM sleep have revealed that this is probably the case. Studies on rats in 2001 showed that the brain-wave activity in mammals during REM sleep was incredibly similar to the patterns of activity shown while awake, suggesting that they were, in fact, experiencing a dream!
What do dogs dream about?
Scientific experiments have revealed that dogs mainly dream about situations that have happened, or might yet occur in their waking life. These range from the mundane to the extreme. For example, a domestic dog may simply dream of chasing after birds in the garden, whereas a guard dog might dream of chasing off an unwanted trespasser!
We know this is the case due to experiments involving the pons. This is a part of the brain stem which paralyses the muscles during sleep.
Without the pons, our bodies would be unable to determine that we were at rest, and so our muscles would probably act out everything we experienced while dreaming!
Which of course, would be a terrible, terrible thing.
But by temporarily disabling a ponsâ paralysing properties, scientists have been able to get a deeper insight into doggy dreams during sleep experiments.
When disabling a dogâs pons, scientists found that canines began acting out their dreams despite being asleep!
The results involved everything weâd already suspected. Dreaming dogs spend most of their time barking at imaginary intruders and running after other animals.
Whether dog dreams ever get more imaginative and unusual is harder to decipher. Not even the most amazing of dog muscles can act out typical human dreams such as flying or falling!
But weâre sure those brainy scientists will discover the answer eventually.
Why do dogs twitch in their sleep?
While we now definitely know their twitches are caused by their dreams, the science behind it is once again to do with the pons! As puppies, dogs have slightly underdeveloped pons. And as older adults, a dogâs pons becomes less efficient. As a result, puppies and older dogs will twitch and woof in their sleep more often than other pups, as the pons canât totally prevent them from trying to act out their dream! Of course, twitches can also still occur in normal adult dogs, but itâs really no different to a human occasionally talking or fidgeting in their sleep!
Does a dogâs breed affect dreams?
Although we canât say for certain, itâs thought that a dogâs breed may actually have an effect on their dream states and also what they are actually dreaming about. Researchers have suggested that the size of a dog is a factor in dream frequency and length, with smaller dogs supposedly dreaming more often than larger pups. But whereas bigger canines donât dream as much, their individual dream episodes are much longer in duration than a smaller dogâs. Pons disabling experiments have also implied that breeds might well be more likely to dream about situations that reflect their instincts. So a pointing dog is more likely to dream about finding game and hunting down animals, whereas a labrador retriever will probably dream about fetch!
