How to stop dog barking

A “Quiet” cue is the single most useful tool for barking of any cause, because it gives you a calm way to tell your dog what you want instead. It is taught entirely with rewards. The ASPCA method, in short: (ASPCA)

1. Let your dog bark three or four times, then say “Quiet” once, clearly and calmly. Never shout: shouting is attention, and attention can reward barking. (ASPCA, VCA)
2. The moment it pauses, feed a steady stream of tiny, pea-sized treats. (ASPCA)
3. Once that is reliable, say “Quiet”, wait 2 seconds of silence, then reward with several treats in a row. (ASPCA)
4. Stretch the gap from 2 seconds to 5, then 10, then 20, over several days or more of training. (ASPCA)
5. Use the cue in real life, with treats kept where barking happens. Merck describes the idea simply: reward staying quiet instead of barking. (Merck)

Some guides, including the ASPCA page this method comes from, add a startle such as a shaken can of coins. AVSAB lists shaker cans, squirt bottles and compressed air among the intimidation tools a trainer should avoid, so this plan leaves them out. (AVSAB)

Barking at visitors, the doorbell, the postman or people walking past is alarm or territorial barking. Dogs bark to warn off people and animals approaching what they see as their territory, and some alarm bark at every noise and sight, whatever the context. (ASPCA, VCA)

Step one: take away the view

• Fit removable window film or a spray-on glass coating to the window your dog watches from, or keep the curtains closed. (ASPCA, RSPCA)
• In the yard, use secure, opaque fencing or screening so passers-by cannot be seen. (ASPCA)
• Keep treats and toys ready, and use them before the barking starts, not after. (RSPCA)

Step two: change how the trigger feels

Desensitisation means exposing your dog to the trigger in small steps, starting with a version so mild that it notices but does not bark: a recorded knock played quietly, or people seen from the far side of a room. Counter-conditioning pairs the trigger with something your dog loves, usually food, so visitors start to predict good things. Raise the intensity gradually, but not in a straight line: mix in easy sessions. (Merck, VCA, Merck)

Step three: give your dog a job

Teach a “go to your spot” at a mat at least eight feet from the front door, build a stay of at least 30 seconds, then rehearse with a helper in mock visits of 5 to 10 minutes. A dog lying on its mat for a reward is not barking at the door. (ASPCA)

Dog barking at night has a short list of causes, and the right fix depends on your dog’s age as much as on the barking itself. In young and adult dogs, look first at spare energy, outside noises and a learned habit of being answered. In older dogs, night barking is a reason for a vet check, because pain, hormone disease and cognitive dysfunction all cause waking at night. (RSPCA, Merck)

Whatever the cause, avoid going to your dog only when it barks, or calling out to quieten it. Any attention, even a telling-off, can reward the barking. Mild punishment merely rewards the behaviour by giving attention. (VCA)

Separation barking is persistent and seems to be triggered by nothing except being left alone. It is common: the RSPCA reports that eight out of 10 dogs experience stress when left alone, and barking is one way it shows. It is distress, not spite, so punishment makes it worse. Barking is one sign of dog separation anxiety, which can also show as pacing and house soiling. (ASPCA, RSPCA, Merck)

• Record your dog while you are out. Separation signs typically begin within the first 15 to 30 minutes, and barking peaks early in the absence. (Merck)
• Give at least 30 minutes of aerobic exercise a day, ideally before you leave. (ASPCA)
• Leave a food-stuffed toy that takes at least 20 to 30 minutes to finish, and pick it up when you return. Highly anxious dogs usually will not eat when alone, which is itself a useful clue. (ASPCA)
• Keep goodbyes and hellos low-key, and practise picking up keys and coats without leaving, since many dogs start to worry as their owner gets ready to go. (ASPCA, Merck)
• Build time alone from one to two seconds, then five to ten, staying below the point at which your dog becomes anxious. (ASPCA)
• If your dog barks constantly in a crate, a crate is the wrong place: try a gated room. (ASPCA)

Moderate or severe separation anxiety needs professional help from a certified applied animal behaviourist or a board-certified veterinary behaviourist, and your vet can talk you through whether medication has a place. (ASPCA, AVSAB)

Barking and lunging at other dogs on the lead looks like aggression, but it is most often driven by fear, frustration or territoriality. The goal is to change how your dog feels about other dogs, not to suppress the warning, and that starts with keeping enough distance that your dog can still think. (Merck)

1. Manage first: walk at quieter times and places, and turn away early. Merck calls management aimed at avoidance essential for safety. (Merck)
2. Learn the early stress signals in dog body language: a tense body, a lowered tail, a lifted front paw, lip licking or yawning. (AVSAB)
3. Find the distance at which your dog notices another dog but does not bark, and work there. Keep the intensity low. (Merck)
4. Each time a dog appears, feed a high-value treat; when the dog goes, the treats stop. That is counter-conditioning. (Merck)
5. Close the distance slowly, with easy sessions mixed in, and never with lead jerks or a prong or shock collar. (Merck, AVSAB)

Attention barking is learned. Dogs bark at people to get food, toys, play or simply a look, and owners often reinforce it without meaning to. The fix is strict: never reward barking with any type of attention, even occasionally. (ASPCA, VCA)

• When your dog barks at you, turn away, look at the ceiling or leave the room. (ASPCA)
• The instant it stops, ask for a sit, then give it what it wanted. (ASPCA)
• Expect a short spell where barking gets worse before it gets better, and a later comeback. Both fade if you stay consistent. (Merck)

Boredom barking looks different: repetitive, with no clear trigger, often from a dog left alone for long stretches. It responds to more exercise, mental stimulation and social contact, and to a daily routine of meals, play and exercise at about the same time each day. Food puzzles, scavenger hunts and learning new tricks all count. (ASPCA, RSPCA, VCA)

In an apartment, every bark is shared with the neighbours, and the triggers come through the walls: footsteps in the hallway, doors closing, lifts, other dogs. The methods do not change, but management matters more, because each bark you prevent is one less rehearsal. (ASPCA, AVSAB)

• Treat hallway noises like a doorbell: play recordings of footsteps and doors very quietly, pair them with food, and turn them up slowly. (VCA, Merck)
• Move your dog’s bed away from the front door and any window onto the street, and use window film where it watches. (ASPCA)
• Use the “go to your spot” mat as the default response to a knock. (ASPCA)
• Front-load the day with exercise, play and a puzzle feeder, so there is less spare energy when you are out. (VCA, ASPCA)
• If a neighbour complains, the RSPCA’s advice for the other side of the wall applies to you too: talk first. Explain what you are doing about it. (RSPCA)

Do not reach for a muzzle to keep an apartment dog quiet. The ASPCA warns never to use a muzzle to stop barking for long periods or when you are not supervising. (ASPCA)

Barking that starts suddenly in an older dog is not a training problem until a vet has said so. Medical problems add to vocalising especially in the older dog, and vets must rule out physical problems, especially pain, before treating any behaviour. (VCA, Merck)

Cognitive dysfunction, the canine version of dementia, is common. Memory decline has been measured from 6 to 8 years of age, and in one study 28% of dogs aged 11 to 12 and 68% of dogs aged 15 to 16 showed signs of it. Experts recommend yearly screening from 7 years. (Merck, VCA)

Signs that point to a medical cause

• Restlessness, trouble settling and waking at night, which pain can cause. (Merck)
• Excessive vocalising, disorientation, house soiling, new fears or worsening separation distress, all listed signs of cognitive dysfunction. (VCA)
• Barking with a change in hearing or sight. Sensory decline can cause vocalising. (Merck, RSPCA)
• Panting and night waking, which can also come from hormone disease. (Merck)

Many diseases look like cognitive dysfunction, so only a vet can confirm it. If it is confirmed, treatment starts with enrichment: old tricks, new tricks, puzzle toys, scavenger hunts, safe exercise, traction rugs and night lighting. Punishment is especially unhelpful here, because the anxiety it causes makes learning harder for an ageing brain. (VCA, VCA, Merck)

The American Veterinary Society of Animal Behavior’s position is that reward-based methods should be used for all dog training, including unwanted behaviour such as barking, and that aversive methods, which rely on force, pain or discomfort, should not be used. It links aversive training to increased anxiety, fear-related aggression and avoidance. (AVSAB)

• No shock, prong or choke collars. AVSAB lists them as tools that work through pain. Merck adds that prong and shock collars can make an already aggressive dog worse. (AVSAB, Merck)
• No citronella or spray collars. The ASPCA calls anti-bark collars punishment devices that are not a first choice, whether the stimulus is a noise, a citronella spray or a shock. VCA notes they only work while the dog wears one and may soon stop working without training. (ASPCA, VCA)
• No shouting, squirt bottles or shaker cans. AVSAB lists all three among the intimidation tools to avoid. Some guides, VCA’s among them, still suggest owner-operated sprays and shake cans; this plan follows AVSAB and leaves them out. (AVSAB, VCA)
• No punishment for fear or anxiety barking. Punishment can increase anxiety and aggravate many forms of barking. (ASPCA, VCA)
• No punishing on your return. A dog punished for barking while alone becomes anxious about your return, which makes it worse. (RSPCA, ASPCA)

We looked for an AVMA statement on bark collars to cite alongside AVSAB’s, but could not retrieve one, so this page relies on AVSAB, the ASPCA, VCA, Merck and the RSPCA.

No source gives a single figure, because it depends on the cause and how long the habit has been practised. What the sources do say: (ASPCA, Merck)

• A “Quiet” cue is built up over several days or more of training. (ASPCA)
• Building up time alone for separation barking takes many weeks of daily sessions. (ASPCA)
• Attention barking often gets worse before it gets better once you stop rewarding it, and can come back later. (Merck)
• Some behaviour problems need treatment for a year or longer. (Merck)

So treat the two-week plan from the finder as a first block. Keep the barking log going: if the number of bouts is falling, carry on; if nothing has changed after the plan, the RSPCA’s advice is to ask your vet and then a clinical animal behaviourist. (RSPCA)

Have your dog examined before you work on barking that is new, sudden or out of character, at any age. The ASPCA recommends ruling out medical causes first, and the RSPCA names hearing problems as one to check. For an older dog, book the appointment before you start the plan. (ASPCA, RSPCA)

No source gives a fixed number of days after which barking becomes a medical worry, so if you are unsure, call your vet to be safe. Go back to your vet, too, if barking comes from fear or anxiety that is not improving: these need a treatment plan that can include behaviour modification and, in some cases, medication. (AVSAB)
