Why Dogs Stay Awake at Night

Puppies and Nighttime Wakefulness

Young puppies often wake during the night because their bladders are small and they need to eliminate. If they cry and receive attention, they learn that waking up gets them what they want—your time and care. This can create a habit that lasts beyond puppyhood. To prevent this, respond only when necessary (to take them outside), and avoid giving attention during the night unless it’s urgent. Over time, this teaches the puppy to stay quiet and sleep through the night.

Older Dogs and Disrupted Sleep

As dogs age, they may develop a pattern of waking and wandering at night. This can be due to cognitive dysfunction (CDS), which commonly causes nighttime restlessness, disorientation, and anxiety. Pain from joint disease or other health issues can also make it hard for older dogs to sleep comfortably. Additionally, sensory decline—like hearing or vision loss—may disrupt their sleep-wake cycle and increase nighttime activity. Poor sleep can worsen cognitive issues, creating a cycle of worsening behavior.

Sleep Patterns and Natural Rhythms

Dogs naturally have more sleep-wake cycles than humans. On average, they sleep for about 16 minutes, then wake for 5 minutes, repeating this cycle throughout the night. This is normal, especially in dogs left to their own devices. However, dogs living with people tend to sleep more at night. Their sleep includes both slow-wave and REM phases, during which they may twitch or vocalize—likely dreaming. This natural rhythm means dogs are more alert at night than humans expect.

Lack of Daytime Stimulation

Dogs that don’t get enough physical or mental activity during the day may become restless at night. This is especially true for dogs that sleep a lot during daylight hours. Without sufficient exercise, training, or enrichment, they have excess energy and mental stimulation needs. Providing short walks, puzzle toys, sniffing games, and training sessions during the day helps tire them out and promotes better nighttime sleep.

How to Help Your Dog Sleep Through the Night

To reduce nighttime wakefulness, focus on daytime routines. Increase exposure to daylight, provide mental challenges, and avoid rewarding nighttime behavior with attention. If your dog wakes, ignore them until they are quiet—or use calm commands like “sit” or “lie down.” For older dogs, consult a vet about possible medical causes like CDS or pain. Supplements like melatonin or pheromones may help, and in some cases, medication like selegiline is recommended. The key is consistency and addressing the root cause.
