Dog Anxiety at Night: Causes, Solutions & When to Call the Vet
Dogs that pace, whine, pant, or destroy things after dark are often suffering from anxiety — not misbehaving. Nighttime anxiety in dogs can stem from pain, cognitive decline, hearing loss, or fear, and getting to the root cause is the first step toward helping your dog (and yourself) sleep.

Why Is My Dog Anxious at Night?
Nighttime anxiety in dogs is more common than most owners realize, and it frequently worsens with age. The most important first step is identifying the trigger, because treatment differs dramatically between causes.
Pain: Arthritis, IVDD, and other painful conditions are dramatically worse at night when dogs can no longer distract themselves with activity. A dog who was fine during the day but begins restless pacing after dark should be evaluated for a pain source. As outlined in the AAHA Pain Management Guidelines, 2022, pain is significantly under-recognized in dogs, and nighttime behavioral changes are a key indicator.
Canine Cognitive Dysfunction (CCD): Often called "doggy dementia," CCD causes disorientation, anxiety, altered sleep-wake cycles, and nighttime vocalization, particularly in dogs over 11 years old. According to the AAHA Canine Life Stage Guidelines, 2019, signs of cognitive dysfunction are present in approximately 28% of 11-to-12-year-old dogs and 68% of dogs aged 15–16.
Sensory decline: Dogs with age-related hearing or vision loss may startle more easily in the dark, become disoriented, or lose their ability to locate reassuring sounds and sights that anchor them during the day.
Separation anxiety: Some dogs tolerate being alone during the day but struggle with the perceived isolation of nighttime — especially if their routine has changed (new home, new work schedule, or a family member away).
Fear/phobia: Thunderstorm phobia, fear of outdoor sounds, or anxiety triggered by specific environmental factors that peak at night (raccoons, neighborhood sounds, weather changes).
What Helps Dog Anxiety at Night
Matching the intervention to the cause matters. General strategies that help most forms of nighttime anxiety:
Increase daytime exercise: A well-exercised dog sleeps more soundly. Aim for 30–60 minutes of active exercise based on your dog's age and breed. Mental stimulation (puzzle feeders, training sessions, sniff walks) matters as much as physical exercise.
Create a consistent bedtime routine: Dogs thrive on predictability. A consistent last outing, a brief calm interaction, and a designated sleeping spot help signal that nighttime is safe and settled.
Sleeping proximity: Anxious dogs sleep significantly better near their owners. If feasible, allowing your dog to sleep in your bedroom (on their own bed) reduces nighttime anxiety for many dogs.
White noise or soothing music: Studies show that certain types of music (classical, reggae, or species-specific calm music) reduce anxiety behaviors in dogs. A white noise machine can also muffle triggering outdoor sounds.
Anxiety wraps: Pressure garments (ThunderShirt) may help some dogs, particularly those with storm or noise phobia.
Calming supplements: Products containing L-theanine, melatonin, or alpha-casozepine have evidence supporting mild anxiolytic effects in dogs. Discuss with your vet before use, particularly if your dog is on other medications.
Prescription medications: For moderate to severe anxiety, your vet may recommend trazodone, gabapentin (especially if pain is also a factor), or an SSRI such as fluoxetine for long-term management. These require a veterinary prescription and proper dosing.
When to See a Vet
Call your vet today if:
- Nighttime anxiety started suddenly in a previously calm dog (sudden onset = possible pain or neurological change)
- Your dog is over 10 years old and has started nighttime vocalization, confusion, or pacing
- Anxiety is significantly disrupting your dog's sleep and quality of life
- You've tried management strategies for 2+ weeks without improvement
- Your dog is also showing signs of pain (limping, reluctance to move, yelping when touched)
Go to the ER immediately if:
- Your dog is panting heavily, restless, and has a distended abdomen (possible bloat)
- Your dog appears disoriented, cannot stand, or has had a seizure
- There is any evidence of trauma or injury

Frequently Asked Questions
Is my senior dog's nighttime anxiety normal? Nighttime restlessness in dogs over 10 is common but never "just aging" — it almost always has a treatable cause such as pain, CCD, or sensory decline. A senior wellness exam with bloodwork is an important first step for any dog whose nighttime behavior has changed.
Can I give my dog melatonin for nighttime anxiety? Melatonin is generally considered safe for dogs at 1–6 mg depending on size, given 30–60 minutes before bed. Ensure the product is xylitol-free. It may help anxiety related to sleep-wake disruption or noise phobia. Talk to your vet about the appropriate dose for your dog.
Should I get my anxious dog a companion animal? A second dog sometimes helps, but often does not resolve the underlying anxiety and may add a second anxious dog to your household. Address the root cause first.
What does anxiety medication for dogs cost? Trazodone costs approximately $15–40/month depending on dose. Fluoxetine (generic) is $20–50/month. A behavioral consultation with a veterinary behaviorist runs $200–500 for the initial appointment. Many general practitioners can manage mild-to-moderate anxiety without a specialist referral.
Can my dog's nighttime anxiety get better without medication? Yes — many dogs improve substantially with environmental modification, exercise, routine, and addressing underlying pain or sensory loss. Medication is most helpful for moderate to severe cases where behavioral interventions alone are insufficient.
