Why Is My Dog Barking at Night? Causes and Fixes

Night barking is exhausting because it hits when everyone is trying to sleep. The good news is that the causes are usually easy to narrow down. This guide is part of our complete guide on how to stop a dog from barking, which covers every type of barking in more depth.

Why do dogs bark at night?

Likely cause	Clues	What to try
Needs to go outside	Puppy or older dog; heads to the door when you get up	Last potty break right before bed; for new puppies, expect night trips in the first weeks (PetMD)
Outside noises or sights	Barks at specific sounds, ears up, runs to the window or door	Close the curtains or move the bed to another room (Humane World); music to mask other dogs barking (ASPCA)
Not tired enough	Restless, wants to play, barks at you	More exercise and brain games during the day (Humane World)
Wants attention	Barks at you, stops the moment you respond	Once needs are met, don’t reward the barking (ASPCA)
Pain or cognitive change	Senior dog, new habit, confused or restless	Veterinary check

How to stop your dog barking at night

1. Book a vet check if the barking is new. The ASPCA notes that dogs sometimes bark in response to pain, and recommends a veterinary exam to rule out medical causes before you start training.
2. Plan the last potty break. Take your dog out right before bed and wait until they actually go. Humane World for Animals puts daytime bladder control at roughly one hour per month of age, and notes that most puppies can comfortably sleep for seven hours without a bathroom break. In the first few weeks, though, PetMD says to expect to take a new puppy out a few times a night.
3. Use the day well. Humane World for Animals notes that a tired dog is less likely to bark from boredom or frustration. For puppies, PetMD recommends playtime in the hours before bed, then about an hour to calm down.
4. Deal with what your dog hears and sees. If your dog barks at sounds or sights outside, close the curtains or move their bed to another room, as Humane World for Animals suggests. The ASPCA suggests playing music to drown out the sound of other dogs barking.
5. Stay boring at night. If your dog wakes you, Humane World for Animals advises staying calm, taking them out quietly and returning them to bed without turning it into playtime.
6. Reward the quiet. If your dog barks at night for attention and you’re sure their needs are met, the ASPCA says to consistently not reward the barking: ignore it. Reward the quiet instead, waiting until your dog has stopped, even for a second (Humane World).

A bedtime routine, step by step

PetMD suggests planning the evening around bedtime. Its plan is written for puppies:

1. Dinner about four hours before bed. PetMD gives the example of dinner around 5 p.m. for a 9 p.m. bedtime.
2. Active play two to three hours before bed. Tire your dog out with a game or a walk.
3. An hour of quiet time. Let your dog wind down before bed. A chew or a food puzzle from our guide to mental stimulation can fill this hour.
4. A short potty trip right before bed. Go to the usual spot and wait until your dog has finished. Our house training guide covers potty schedules in detail.

Puppy crying or barking in the crate at night

PetMD notes that it’s very common for puppies to cry their first few nights, or even weeks, at home, because until now they’ve slept next to their mother and littermates.

• Put the crate close by. Humane World for Animals suggests your bedroom or a nearby hallway at first, so you can hear when your puppy needs to go out. PetMD adds something that smells like you, such as a recently worn T-shirt.
• Read the timing. According to PetMD, crying early, when your puppy first goes into the crate, is more often about settling in, while crying in the middle of the night more likely means they need to go. PetMD says puppies can typically hold it for about 4 to 6 hours overnight.
• Test with “go potty.” Humane World for Animals suggests ignoring whining for several minutes if your puppy has never been let out for it. If it continues, say your “go potty” phrase; if your puppy responds eagerly, take them out. It should be a trip with a purpose, not playtime.
• Never punish. Humane World for Animals says never to punish a puppy for whining, and PetMD warns never to use the crate as punishment.

Our puppy training guide covers the whole first night, and crate training step by step.

Barking at noises outside

The ASPCA calls barking at any and every noise and sight, regardless of the context, alarm barking. At night that might be car doors, footsteps, a neighbor’s dog or wildlife in the yard. Management comes first: close the curtains, move your dog’s bed to a quieter room, and use music to mask other dogs barking. If your dog still reacts to a specific sound, such as a neighbor’s dog, our barking guide explains how to desensitize a dog to a sound step by step, using the doorbell as its example. For daytime triggers at the front door, see our guide to stopping barking at the door.

Night log

Before you change several things at once, write down what happens. Our barking guide has a three-day barking log; for night barking, these columns are enough:

Night	Time of barking	What happened just before	How you responded	What happened next
Example: Thu	2:10 a.m.	Car door outside	Stayed in bed	Stopped after a minute

Common mistakes

• Shouting from bed. Humane World for Animals notes that yelling at your dog to be quiet won’t reduce their barking.
• Ignoring a puppy who may need to go. Young puppies often genuinely need a night trip. Use the “go potty” test instead of assuming the barking is for attention.
• Getting up to play or feed. Humane World for Animals advises returning your dog to bed without turning night trips into playtime.
• Skipping the vet with a senior dog. New night barking in an older dog is a health question first.

Night barking by age

Puppies often cry and need night trips in the first weeks. Follow the crate section above; PetMD notes that crying is common in the first few nights or weeks at home.

Adult dogs who suddenly start barking at night may have a new trigger, such as a new neighbor’s dog, wildlife in the yard or a change in routine. Your night log will point to it.

Senior dogs may bark at night because of pain or cognitive dysfunction. VCA Animal Hospitals lists waking at night and disrupted sleep, and excessive vocalization, such as barking at nothing, among the signs, along with disorientation and house soiling. VCA recommends regular exercise, interactive toys and play alongside veterinary care; ask your veterinarian about diet and anything else that might help.

When to get help

If your dog barks, pants and paces at night and seems anxious rather than bored, a veterinarian or a qualified behavior professional can help you build a plan. If the barking happens only when you’re away, our guide to dog separation anxiety explains the signs and the first steps. Humane World for Animals suggests a certified professional dog trainer if the tips above don’t help.
