Nighttime Hyperactivity in Dogs: Solutions for Restless Behavior

Why Dogs Wake Up at Night

Dogs naturally have more sleep–wake cycles than humans—on average, 23 cycles per eight-hour night, with each sleep phase lasting about 16 minutes. This means dogs are frequently awake during the night, even when not acting out. However, when this wakefulness turns into barking, whining, or pacing, it often signals a deeper issue. Common causes include insufficient daytime activity, changes in the sleep–wake cycle due to aging, or medical conditions like cognitive dysfunction syndrome (CDS) or joint pain. In older dogs, sensory decline—especially vision or hearing loss—can disrupt sleep patterns and increase nighttime restlessness.

Fix the Daytime Routine First

The foundation of better nighttime behavior starts during the day. Dogs that are restless at night often lack enough physical and mental stimulation. Experts recommend increasing exposure to daylight, even through short outdoor activities, to help regulate the sleep–wake cycle. Enrichment activities such as puzzle toys, food-hiding games, training sessions, and interactive play (like tug or fetch) can keep dogs mentally engaged and physically tired. These activities not only prevent boredom but also support brain health. Even dogs with limited mobility can benefit from modified exercises, such as short walks or sniffing games, to maintain activity levels.

Avoid Reinforcing Nighttime Behavior

When a dog wakes up and vocalizes at night, the instinct may be to comfort or take them outside. However, this unintentionally rewards the behavior. According to behavior experts, the best approach is to ignore the dog until they are quiet. If the dog is already awake, using simple commands like “sit” or “lie down” can help settle them without giving attention. Punishment or frustration only increases anxiety. For puppies, a neutral nighttime response—ignoring whining, then taking them out only if necessary—can prevent learned behavior of waking up for attention. The goal is to teach the dog that nighttime is for sleeping, not interaction.

Address Aging and Health Issues

Older dogs often wake up at night due to cognitive dysfunction (CCD), which affects sleep patterns and causes disorientation, anxiety, or restlessness. Signs include increased nighttime activity, confusion, and decreased interest in play. Pain from joint disease or other sources can also prevent comfortable sleep, creating a cycle where poor sleep increases pain perception. Additionally, aging dogs may struggle to regulate body temperature and can become cold at night, especially in unheated sleeping areas. Sensory decline—such as vision or hearing loss—may contribute to nighttime anxiety and disrupted sleep. A vet should evaluate any sudden or worsening nighttime behavior in older dogs.

When to Use Supplements and Medication

For persistent nighttime restlessness, especially in older dogs, veterinary guidance is essential. Supplements like melatonin, L-theanine, or pheromones may help reduce anxiety and support sleep. Lavender oil has also been suggested as a calming aid. In cases of cognitive dysfunction, medications like Anipryl (selegiline hydrochloride) can improve alertness and reduce nighttime disturbances. These treatments are most effective when combined with behavioral strategies like routine enrichment and ignoring nighttime wakefulness. Always consult a veterinarian before starting any supplement or medication.
