How to Stop a Dog Barking at Night

The short answer: Most night barking has a simple cause: a potty need, leftover energy, loneliness or noises outside. Take your dog out and tire them out before bed, give them a calm sleep spot near you with white noise, and reward quiet instead of responding to barking. If an older dog suddenly starts barking at night, see your vet.

Common causes of night barking

CauseCluesFix
Needs to go outPuppy, or barking at the same time each nightLast potty break right before bed; a quick, boring trip out if needed
Too much energyLittle exercise during the dayA longer evening walk or a sniffing game

A bedtime routine that works

  1. Evening exercise. 20 to 30 minutes of walking or play an hour or two before bed, adjusted for your dog.
  2. Last potty break. Right before lights out. Keep it calm.
  3. A chew or a puzzle. Licking and chewing are calming for many dogs.
  4. The same sleep spot every night. Somewhere comfortable, away from windows, ideally where your dog can hear or smell you.
  5. Background noise. A fan or white noise machine masks outside sounds.

Puppies vs senior dogs

Puppies

See our puppy crate barking guide. Young puppies often can't hold it all night, and many are lonely in a new home. Putting the crate next to your bed, taking them out calmly when they wake, and going straight back to bed usually settles things within a few weeks.

Senior dogs

If a dog around 9 or older starts barking, pacing or wandering at night, it may be more than a habit. Cornell's Riney Canine Health Center lists night-time roaming, sleeping more during the day, disorientation and new anxiety as signs of canine cognitive dysfunction, which may be underdiagnosed because it comes on slowly. Pain, hearing loss and vision loss can also unsettle a dog at night. Your vet can check for these and suggest treatment.

Barking while asleep is a different thing, and usually normal. See dog barking in sleep.

Common questions

Should I ignore my dog barking at night?

Ignore demand barking, but not barking that may mean your dog needs to go out, is in pain or is scared. Puppies in particular may need a night potty break. Take them out calmly, with no play, and go straight back to bed.

Why has my older dog started barking at night?

New night barking in a senior dog can be caused by pain, hearing or vision loss, or age-related cognitive changes. Cornell's Riney Canine Health Center lists roaming the house at night as a sign of cognitive dysfunction. A vet visit is the right first step.

Can I use a bark collar at night?

We don't recommend it. A collar may stop the noise without solving the cause, and a dog that is scared or needs to go out can't tell you.

Brain Training for Dogs is an online course by certified trainer Adrienne Farricelli (CPDT-KA). It uses reward-based games to build focus and self-control, which is what most barking problems come down to. It costs about $47, one time.
