Many researchers believe that dogs dream just like humans do, though we still have much to learn about how and why.
Dogs bark, yip, and kick in their sleep, leading many owners to wonder: are they dreaming? Science says yes. Dogs have brain waves similar to humans, and studies (Trusted Source) indicate that dogs sleep (and dream) often like we do. Sleep is vital to your pup’s dreams and overall health, so it’s important for dog owners to be aware of any changes in your pet’s sleep habits, as this could be a sign of an underlying health issue.
Between their naps and overnight snoozing, dogs sleep for 9-14 hours a day. Must be nice! There are two main sleep stages: non-rapid eye movement sleep (NREM) and rapid eye movement sleep (REM). NREM has three categories for people, but it’s simpler when studying sleep in dogs with just NREM and REM sleep. Researchers have studied how dogs take in, process, and store information and how deep sleep works for dogs.
NREM stands for non-rapid eye movement, which both dogs and people experience. People have three types of non-REM sleep, but for dogs and many other mammals, this stage is simply one single part of sleep and is often called slow-wave sleep. Often, dogs wake up from REM sleep rather than enter an NREM sleep cycle before fully waking up.
REM sleep cycles for human beings are essential to our health, but its importance is often overlooked when it comes to our canine companions. Dogs experience the REM stage of sleep just as humans do and for this reason, they can experience abnormalities in their sleep cycle. While this can be caused by illness (such was the case in this study (Trusted Source) surrounding tetanus), for some dogs twitching, running, and other common signs of dreaming are normal behavior.
Tetanus vaccines are not part of a routine vaccine protocol in dogs. Since the most common cause for tetanus is due to wounds from something in the environment. It is important that parents are vigilant of their pets' environment . It is imperative that their dwelling place is free from sharp wires, glass, or wood that could be contaminated. When pets come in from outside, a quick exam should be performed to make sure they don't have any unusual cuts, scrapes or wounds that may need attention.

In some cases, you may be concerned that your dog’s twitches in their sleep may be a seizure. While twitching is considered normal behavior during a canine sleep cycle, seizures are a symptom of epilepsy, a medical disorder that requires veterinary diagnosis and care.
Normal twitching during sleep usually involves the limbs, paws, face, and tail. It’s also common to see slow, rhythmic paddling of the limbs and hear vocalizations during sleep that resemble whining. Dreaming dogs will wake up normally. Seizures, on the other hand, are more common in awake dogs. Symptoms of seizures include a stiff, rigid body, labored breathing, loss of consciousness, urination or defecation, foaming at the mouth, and vomiting. This is generally followed by a post-ictal phase in which a dog may appear confused or disoriented.

There isn’t yet conclusive evidence that dogs dream as humans do. But as scientists observe dogs as they sleep and study the part of the brain structure and waves, many have come to the conclusion that dogs do, in fact, dream. Below are some key points that support this theory.
Scientists believe that dogs dream about the same things humans do. People dream as a way to process emotions and information, and studies show (Trusted Source) that the same type of occurrence happens within dog brains.
Dogs likely dream about their daily experiences or everyday activities, whether that means chasing their favorite ball, or learning new commands. Here are a few examples of vivid dreams your dog might have and what that might look like.
Your dog’s age and size may play a role in how well they sleep, and often they dream in their daily lives.
Puppies spend less time in REM sleep, which means less time during which they may be dreaming. There have been fewer studies into puppies and their sleep patterns, but scientific research indicates that dogs younger than a year old have underdeveloped cognitive functions compared to adult dogs. This may impact puppy dreams, changing what they dream about and how they respond.
Adult dogs are often used to conduct studies surrounding dogs. While inconclusive, some links between dog size, breed, and sleep quality impact dreaming and behavior. Health conditions can also impact sleep and, thus, dreaming. Some dogs, like brachycephalic breeds, are prone to snoring. Other dogs may have trouble sleeping altogether, which can reduce REM sleep and dreams. Since they sleep so often, senior dogs are also likely to dream.
Much like with people, poor sleep habits in dogs can have a direct impact on behavior. This study from 2022 (Trusted Source) shows that dogs that don’t receive enough sleep or are woken up during their sleep cycle may exhibit worse behavior. Dogs who have trouble sleeping may also have a sleep disorder.
Because dogs can dream, that means they can also have nightmares. The signs may be subtle, but there are some concerns to look for when your dog is having a nightmare.
While our first instinct as pet parents is to rouse our pets from nightmares as quickly as possible, waking a dog from a nightmare must be done carefully. Nightmares are scary for dogs, and, just like us, they may wake up scared and become reactive or aggressive before realizing they are no longer in the nightmare. Dogs can accidentally scratch or bite their owners when not woken up correctly.
To wake up a sleeping dog, you should softly call their name until they wake up and settle down. Once your dog knows where they are and who they are with, it’s safe to provide them with love and snuggles to reassure them that they are safe.
Dogs don’t sleepwalk like humans, but they may have active limbs. Dogs dreaming or having nightmares may appear to have a seizure or be in a trance.
Dogs can have dreams and nightmares due to their brain structure and sleep patterns. Dreams (and nightmares) might include vocalizations, twitching, and shaking.
While no one knows what dogs dream about, researchers believe they dream about their experiences and owners. Dogs frequently twitch in their sleep as if chasing squirrels or rabbits. Or, dogs may attempt to chew a favorite toy or bone.
