The short answer: Howling is normal dog communication. Dogs howl to call to other dogs or people, to ask for company or attention, in response to sounds like sirens, and sometimes because of separation anxiety, pain or illness. Don't reward it with attention, teach a quiet cue, and see your vet if the howling is new, sudden or excessive.

Common reasons dogs howl

Reason	What the sources say
Communication	PetMD: dogs descend from wolves, who use howling to communicate over long distances. Dogs may howl to signal their location or invite contact. AKC: it is a normal form of communication with social and emotional meaning.
Attention	Both PetMD and the AKC say dogs learn that howling gets a reaction.
Loneliness, anxiety or separation anxiety	AKC: lonely and anxious dogs often howl, possibly to request company or assistance. PetMD: dogs with separation anxiety often howl when separated from their person.
Sounds like sirens or music	PetMD: dogs may howl at triggering sounds; experts aren't certain why. AKC: high-pitched sounds can resemble howls, so dogs join in.
Announcing presence or territory	AKC: howling in the yard can reach neighborhood dogs or warn off intruders.
Pain or illness	PetMD: a dog may howl if sick or in pain, especially if the discomfort is sudden. AKC: a normally quiet dog that vocalizes more may be unwell.
Breed	PetMD: Huskies, Malamutes and American Eskimos, and hounds bred to bay such as Beagles, Foxhounds and Coonhounds, are more likely to howl.

What to do

Don't reward it. The AKC says to avoid rewarding howling with attention, whether positive or negative.
Teach a quiet cue. Reward quiet behavior with a high-value treat (PetMD). PetMD says they may not obey at first but will learn with patience and consistent training.
Reward calm. The AKC says to reward calm, quiet behaviors so the dog learns other ways to get your focus.
Don't scold. PetMD says scolding may link a trigger such as a siren to a bad experience and lead to anxiety or phobia.
Handle separation howling gradually. If your dog howls mainly when you leave, see barking when left alone. The same step-by-step approach applies.

Howling at night, in sleep or all of a sudden

At night: Neither page we opened covers nighttime howling specifically. Cornell's Riney Canine Health Center lists wandering the house at night and sleeping more during the day as signs of cognitive dysfunction syndrome, which can start around age nine, so see a vet if an older dog changes at night.
In sleep: PetMD says sounds like crying, whining or howling that happen only in sleep are probably nothing if your dog doesn't do them awake. Don't wake a dreaming dog. See dog barking in sleep.
All of a sudden: Sudden howling may mean pain (PetMD). The AKC says to bring your dog to the vet to rule out underlying health issues.

When to see your vet or a trainer

The AKC says to consult your veterinarian or a qualified trainer if howling is new, excessive, or paired with restlessness, destructive behavior or changes in appetite. PetMD says excessive howling or anxiety should be evaluated by a veterinarian, and that a behaviorist may help. In rural areas howling may not be a problem, but near neighbors it may need addressing (PetMD). See neighbor or landlord complaints.

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.

Common questions

Why is my dog howling?

PetMD's vet author says dogs descend from wolves, who use howling to communicate over long distances. Dogs may howl to signal their location, get attention, express excitement or distress, respond to sounds such as sirens or music, or because of separation anxiety, pain or illness.

Why is my dog howling all of a sudden?

PetMD says a dog may howl if sick or in pain, especially if the discomfort is sudden. The AKC says that for a sudden change you should bring your dog to the vet to rule out underlying health issues.

Why is my dog howling at night?

Neither PetMD nor the AKC page we opened covers nighttime howling specifically. Think through the usual reasons: loneliness or anxiety, responding to sounds outside, attention, and pain. In an older dog, Cornell lists wandering the house at night as a sign of cognitive dysfunction, so involve your vet.

Why does my dog howl in their sleep?

PetMD says sounds that happen only during sleep, such as crying, whining or howling, are probably nothing if your dog doesn't do them when awake. Don't wake a dreaming dog, since it can be confusing and disorienting.

How do I stop my dog howling?

Don't reward it with attention, positive or negative, and teach a quiet cue (AKC, PetMD). Reward quiet with a treat. Don't scold, because PetMD says scolding may link the sound to a bad experience and lead to anxiety or phobia.

Why do dogs howl at sirens?

PetMD says experts aren't certain. One theory is that the dog thinks the siren is another dog and responds. Another is that the dog sees it as a threat and howls to warn you. Howling alone doesn't mean the sound hurts your dog; look for stress signs like hiding, shaking or lip licking.
