Twitching during sleep is common in newborn puppies and is usually nothing to worry about. The twitching may be related to muscle development, neural development, or the REM stage of sleep. Puppies spend more time in the REM stage of sleep than adult dogs, and this is when we tend to dream. Twitching during sleep can look like a seizure, but it is usually just a sign of a puppy dreaming about chasing rabbits or playing.

What You'll Learn
Twitching is a common occurrence in newborn puppies
While the exact reason for twitching in newborn puppies is not fully understood, several theories have been proposed. One theory suggests that twitching helps to exercise the puppy's muscles, increasing muscle tone and strength, which is essential for their development. Additionally, twitching may play a role in the development of the nervous system, as suggested by Howard Roffwarg, who questions the potential connection between twitches and neural development.
Mark Blumberg, a psychology professor at the University of Iowa, conducted experiments on newborn rats and found that whisker twitching triggered bursts of activity in different brain regions. This suggests that twitching may be related to brain development and function. However, more research is needed to fully understand the phenomenon of twitching in newborn puppies.
It is important to note that while twitching during sleep is usually normal, there may be cases where it could indicate a seizure or other health concern. If you are concerned about your puppy's twitching, it is always best to consult a veterinarian for advice and to ensure the puppy's health and well-being.

Twitching may be linked to muscle development
It is normal for newborn puppies to twitch in their sleep. This phenomenon is attributed to dreaming during REM sleep, which is when we tend to dream as well. Puppies spend more time in the REM stage of sleep compared to adult dogs.
The twitching may be linked to muscle development. Veterinarians Liz Palika and Debra Eldredge explain that muscle twitching helps increase muscle tone, allowing puppies to gain enough strength in their legs to stand. This is supported by studies on rats, which found that muscle twitches during sleep helped program cells in the spinal cord responsible for the withdrawal reflex, a reflex meant to protect our bodies from damaging stimuli.
Additionally, Howard Roffwarg, director of the Sleep Laboratory at the New York State Psychiatric Institute, questions whether twitches play a key role in the development of the nervous system. This suggests that twitching may have a more complex role in neural development, which can impact muscle development and other areas of growth.
While the exact reasons for twitching are still unknown, it is believed that the intensity of twitching during early puppyhood and its decrease as the puppy grows indicate a connection with development. This is supported by the observations of Mark Blumberg, a psychology professor at the University of Iowa, who found that whisker twitching in newborn rats triggered bursts of activity in different brain regions.

Twitching could be related to neural development
The twitching of newborn puppies during sleep is a phenomenon that has sparked curiosity and concern among pet owners. While it may sometimes resemble a seizure, it is generally considered normal behaviour. Puppies tend to experience more rapid-eye movement (REM) sleep compared to adult dogs, and during this stage, they may twitch, vocalize, and exhibit rapid eye movements, indicating that they are dreaming.
The question of why puppies twitch during sleep remains a subject of ongoing exploration. One theory that has gained traction suggests a potential link between twitching and neural development. This theory is supported by the observation that twitching is more prominent during the early stages of a puppy's life and diminishes as they grow older, indicating a possible correlation with their developmental stages.
Mark Blumberg, a psychology professor at the University of Iowa, conducted experiments on newborn rats that offer intriguing insights. His research revealed that twitching whiskers triggered bursts of activity in various brain regions. These findings suggest that twitching may play a role in stimulating brain activity and neural development in young animals.
Further support for the neural development theory comes from studies on human babies. Howard Roffwarg, director of the Sleep Laboratory at the New York State Psychiatric Institute, questioned whether twitching could be crucial for the development of the nervous system. He proposed that twitching might facilitate the programming of cells in the spinal cord, specifically those responsible for protective reflexes, such as withdrawing your hand from a hot surface.
While the exact reasons for puppies' twitching during sleep remain partially veiled, the notion that it is related to neural development holds scientific merit. The twitching may serve a functional purpose in the maturation of their nervous system and reflexes, contributing to their overall growth and adaptation to the surrounding environment.

Puppies are often in the REM stage of sleep
Puppies tend to spend a lot of time sleeping, especially when they are newborn. When they are only 2 weeks old, puppies are in the neonatal phase and will tend to sleep 90% of the time. During this time, they will often enter the REM (rapid eye movement) stage of sleep, which is when humans dream. Puppies spend more time in the REM stage of sleep compared to middle-aged dogs.
Puppies often twitch, kick, and move their legs during the REM stage of sleep, which can look like they are running or playing. They may also make small barks or yelps. This is because their large muscle sleep paralysis mechanism is weaker than that of humans, so they act out their dreams. This is perfectly normal and is not a cause for concern. In fact, it is believed that the twitching helps to exercise their muscles and increase muscle tone, aiding in the development of the nervous system and muscle strength.
Some people believe that the twitching is a survival mechanism, as it allows puppies to wake up more easily and be ready for action if they sense any danger. It is also thought that sleep is when dogs process their activities and what they have learned during the day. Therefore, it is important to let sleeping puppies lie and not interrupt their sleep.
While twitching during sleep is common and typically nothing to worry about, if you are ever concerned, it is always best to gently stroke your puppy to calm them or consult your veterinarian.

Twitching lessens as the puppy grows older
It is not uncommon for puppies to twitch in their sleep. This phenomenon is known as "activated sleep", and it occurs during the REM (rapid eye movement) stage of sleep, when puppies tend to dream. Puppies spend more time in the REM stage compared to adult dogs, and their sleep paralysis mechanism is weaker, allowing them to act out their dreams through twitching, vocalizations, and rapid eye movements.
While the exact reason for this twitching is not fully understood, it is believed to lessen as the puppy grows older. This observation suggests a potential connection between twitching and the development of the puppy. Psychologist David Foulkes, an expert on pediatric dreaming, proposes that babies might not dream during their first years of life due to their limited experiences and brain immaturity.
The twitching observed in newborn puppies could be related to similar factors, with the intensity of twitching decreasing as the puppy's nervous system matures and develops. Additionally, the twitching may serve a functional purpose in muscle development and neural development. According to veterinarians Liz Palika and Debra Eldredge, muscle twitching helps increase muscle tone, allowing puppies to gain the leg strength they need to stand.
Further supporting the idea of a developmental connection, Mark Blumberg, a psychology professor at the University of Iowa, found that twitching whiskers in newborn rats triggered bursts of activity in different brain regions. While the specific reasons for twitching in puppies require further research, the available evidence suggests that it is a normal part of their growth and development, and the frequency of twitching is expected to decrease as they mature.
