Why Do Dogs Bark in Their Sleep: 5 Reasons Behind This Behavior

Just like humans, dogs experience different stages of sleep, including REM (Rapid Eye Movement) sleep, which is the stage of sleep where dreaming occurs.

During this stage, a dog's brain can become quite active, which may cause them to bark, growl, or make other noises. Here are five factors that can contribute to this behavior:


Dogs have excellent memories and can remember events that happened weeks, months, or even years ago. During sleep, they recall an event that led to the barking voice.

Memory Recall


Dogs, like humans, experience periods of muscle movement during sleep. Sometimes, the movement can be vocal, such as barking or whining.

Remnants of Sleep-Related Movement


Some dogs may bark as a way to get their owners' attention. This may be a learned behavior if the dog has been rewarded with attention or treats in the past for barking during sleep.

Attention-Seeking Behavior


Dogs need mental and physical stimulation to stay healthy and happy. If a dog is bored or not exercised, he may be more likely to bark in his sleep as a way to release pent-up energy.

Lack of Stimulation


As dogs age, they may experience cognitive decline, which can lead to confusion or disorientation. This can cause them to bark in their sleep as they try to make sense of their surroundings.
