Can Dogs Cry in Dreams? Exactly What to Expect

Dogs are known for their incredible ability to express emotions, whether it’s through wagging tails, playful antics, or sad puppy eyes. One question that often arises among dog owners and enthusiasts is whether dogs can cry in their dreams. 

As our understanding of canine cognition and behavior expands, it’s essential to delve into the complex realm of canine sleep and dreams. 

In this article, we will explore the emotional lives of dogs during slumber, the science behind their dreams, and the possibility of tears shed in their dreamscapes.

Understanding Canine Sleep 

Like humans, dogs experience different stages of sleep, including slow-wave sleep (SWS) and rapid eye movement (REM) sleep. 

During SWS, dogs enter a deep, restorative sleep, while REM sleep is characterized by vivid dreams and increased brain activity. 

While there is limited research specifically examining canine dreams, similarities between the brain structures and sleep patterns of dogs and humans suggest that dogs may indeed have dreams.

The Emotional World of Dogs

Dogs are highly social animals that experience a range of emotions, including joy, fear, and sadness. They can also exhibit empathy and a sense of attachment to their human companions. 

Observations of dogs’ behavior during sleep indicate that they may be capable of dreaming about events and emotions from their waking lives.

Several studies have demonstrated that dogs show physiological and behavioral reactions to emotional stimuli. 

For example, they exhibit increased heart rate and cortisol levels when exposed to stressful situations.

If dogs can dream, it is reasonable to assume that they might also dream about emotional experiences, including moments that may evoke tears during their slumber.

Dreaming and Crying in Dogs

The notion of dogs shedding tears in their dreams raises interesting questions about the physiological and anatomical aspects of crying. 

Dogs have tear glands that produce tears to keep their eyes moist and maintain eye health. 

However, the act of crying, as humans understand it, involves emotional and psychological responses that extend beyond the production of tears.

While dogs can experience emotions, they may not possess the same cognitive and psychological processes associated with human crying. 

Dogs rely more on non-verbal cues and body language to communicate their emotions. Their dreams might involve vocalizations, twitching, or movements but not necessarily actual tears.

It’s important to note that the absence of physical tears in canine dreams does not discount the possibility of dogs experiencing emotional distress during their dreams. 

Dogs may express their feelings through body language and vocalizations, which can be indicative of sadness or anxiety. 

However, whether these emotional experiences during dreams are intense enough to evoke tears remains a topic that requires further scientific investigation.

Interpreting Canine Dreams

Deciphering the content and meaning of canine dreams is a challenging task, as we cannot directly ask dogs about their dream experiences. 

However, behavioral observations and scientific studies provide insights into potential dream scenarios. 

Dogs often exhibit movements and behaviors during sleep that correspond to their daily activities, such as running, barking, or tail wagging. This suggests that they may be reenacting familiar experiences or processing memories.

Dreams may also serve a function in consolidating learning and memory. Dogs could potentially dream about their interactions with other animals, their favorite toys, or even their human companions. 

These dreams may help dogs make sense of their experiences, facilitate memory formation, and provide mental stimulation during sleep.


The question of whether dogs can cry in their dreams remains open to interpretation. While dogs do not possess the same physiological responses as humans when it comes to crying, their emotional lives are rich and complex. 

Their dreams likely involve a range of experiences, including emotions that may manifest through body language and vocalizations. 

Understanding the intricacies of canine sleep and dreams is an ongoing area of scientific research that will shed more light on the emotional world of our beloved four-legged companions. 

As dog owners, it’s important to continue observing and interpreting their behavior during sleep, allowing us to appreciate the depth of their emotional experiences.
