Newborn puppies, like human babies, tend to jump in their sleep. This phenomenon is known as hypnic jerks in babies and is considered a normal part of falling asleep. While the exact reason for this behaviour in newborn puppies is not yet fully understood, there are several theories and ongoing research exploring this topic. One theory suggests that muscle twitching in puppies helps strengthen their muscles and brains, contributing to their healthy development. Another theory speculates that twitching plays a role in the development of the nervous system. While it can be concerning for new pet parents to witness their puppy jumping in their sleep, it is generally considered a normal part of their growth and development.

What You'll Learn
Dreaming and brain development
The twitching and jumping of newborn puppies in their sleep is a phenomenon that has sparked curiosity and scientific exploration. While the exact reason remains unknown, it is generally believed to be associated with dreaming and brain development.
The sleep phase during which puppies exhibit twitching, kicking, and jumping is known as "activated sleep" or REM (rapid-eye movement) sleep. During this phase, puppies may appear to be dreaming, and their bodies can move as if they are walking or running. Similar to human babies, puppies' eyes typically open when they are about two weeks old, but twitching can occur much earlier, indicating a potential connection with brain development.
Research suggests that puppies, like human infants, have more frequent periods of REM sleep, resulting in more active sleep patterns. This activity during sleep is believed to be developmentally advantageous, as it allows their brains to consolidate information and process their daily experiences. Puppies' brains are similar in structure to human brains, and they go through comparable sleep stages and electrical activity patterns, reinforcing the notion that puppies dream.
The twitching and jumping movements observed in sleeping puppies may serve multiple purposes. One theory suggests that these movements contribute to muscle development, helping puppies strengthen their muscles and gain sufficient strength to stand and walk. Additionally, twitching may play a role in the development of the nervous system, as observed in studies on newborn rats, where whisker twitching triggered bursts of activity in different brain regions.
While we cannot know exactly what puppies dream about, experts like Harvard psychologist Deirdre Barrett speculate that they dream about their everyday experiences, including interactions with their owners. This hypothesis is supported by observations of breed-specific behaviors during sleep, such as pointing in Pointers and flushing behavior in English Springer Spaniels.

Muscle development
While there is no definitive answer as to why newborn puppies jump in their sleep, there are several theories that relate to muscle development.
One theory is that the twitching and jumping is a result of the puppy's brain stem sending signals to relax its muscles. This is similar to the hypnic jerks that human babies experience as they relax their muscles into sleep. The puppy's brain stem may be underdeveloped, resulting in involuntary muscle spasms. These twitches and spasms ultimately exercise the muscles and help increase muscle tone, allowing the puppy to gain the strength it needs to stand.
Another theory is that the twitching is related to neural development. Studies on newborn rats have shown that whisker twitching triggers bursts of activity in different brain regions. This suggests that muscle twitching during sleep could play a role in the development of the nervous system, which is connected to muscle development.
Additionally, the twitching may be a sign of dreaming. Puppies are active dreamers, and the jumping could be a physical response to dream images, such as chasing a squirrel. Dreaming is important for brain development, and the frequent periods of REM sleep that puppies experience may be developmentally advantageous.
Overall, while the specific reasons for newborn puppies jumping in their sleep are not fully understood, it is clear that this behaviour is a normal and healthy part of their development, particularly in terms of muscle strengthening and neural growth.

Nervous system development
While there is no definitive answer to why newborn puppies jump in their sleep, there are several theories that suggest a connection with nervous system development.
One theory suggests that muscle twitching in puppies is essential for strengthening their muscles and brains. The twitching helps increase muscle tone, allowing puppies to gain the strength necessary to stand and walk. This theory is supported by veterinarians Liz Palika and Debra Eldredge, who explain that muscle twitching plays a vital role in muscle development.
Additionally, studies on newborn rats have shown that whisker twitching triggers bursts of activity in different brain regions. Similar brain activity has been observed in sleeping puppies, indicating a potential connection to their nervous system development.
Another theory posits that the brain stem of puppies may be underdeveloped, causing them to twitch and jump in their sleep. The brain stem, specifically the pons and medulla, is responsible for sending signals to relax muscles during sleep. If this area is not fully mature, it could result in the involuntary movements observed in newborn puppies.
Furthermore, the frequency of REM sleep in puppies and the similarity of brain wave patterns to those of humans suggest that their sleep patterns are associated with dreaming. During REM sleep, puppies may experience dreams that trigger muscle twitches and jumps.
Overall, while the exact reason for newborn puppies' sleep jumping remains unknown, the available evidence suggests a strong link to their nervous system development. This phenomenon is considered a normal part of their healthy growth and development, and it helps them strengthen their muscles, brains, and overall nervous system.

Nightmares and night terrors
While it is unclear whether newborn puppies jump in their sleep, they do exhibit twitching during sleep. This twitching is believed to be associated with dreams, and it is common and normal for puppies to twitch their tails or their entire bodies, bark, or even jump during sleep.
Puppies may also twitch during nightmares or night terrors. While it can be distressing to observe, it is generally advised not to wake your puppy unless they are clearly in distress. If you need to wake them, gently call their name until they respond. It is important to avoid touching a puppy experiencing night terrors, as you may risk getting bitten.
The occurrence of twitching during sleep in puppies is believed to be a part of their healthy development. According to veterinarians Liz Palika and Debra Eldredge, muscle twitching helps to increase muscle tone and strengthen the puppy's legs, enabling them to stand. Additionally, Howard Roffwarg suggests that twitches may play a crucial role in the development of the nervous system.
While puppies may experience nightmares or night terrors, it is important to remember that twitching during sleep is a normal part of their development. If you are concerned about your puppy's sleep habits, it is always a good idea to consult your veterinarian for advice and guidance.

Seizures and other disorders
While twitching during sleep is normal for newborn puppies, there are some sleep-related behaviours that could indicate a more serious health issue.
Newborn puppies are susceptible to a range of health problems, including genetic disorders. These can cause cognitive issues and metabolic complications that severely impact a puppy's quality of life. For example, juvenile hypoglycaemia is a genetic disorder that makes it difficult for puppies to gain and maintain a healthy weight. Other congenital disorders can also cause puppies to sleep separately from their litter, as the mother may instinctually reject them. If you notice your puppy sleeping away from the rest of the group, you should consult a veterinarian.
Sudden changes in sleep patterns, such as excessive tiredness or refusal to sleep, could indicate an underlying health problem. Restlessness, or difficulty settling down when they should be sleeping, can also be a cause for concern. Puppies with respiratory issues or allergies may experience breathing difficulties during sleep. Increased crying, weight loss, decreased appetite, vomiting, fever, and other infectious agents can also be signs of a serious health problem.
If you are concerned about your puppy's sleep habits, it is important to consult a veterinarian. They can help identify any underlying conditions and provide advice on establishing a healthy sleep routine for your puppy.
