How do I stop my puppy barking at other dogs?

The short answer

First work out whether your puppy is excited or worried. A bouncy, pulling, whining puppy wants to reach the other dog; one that leans back, tucks its tail or hides behind you is unsure. Either way, step back until your puppy can see the dog and still take a treat, reward calm looking, and keep greetings short and rare. Telling it off only adds stress. Kroki, a reward-based training app for puppies and dogs, has a step for meeting other dogs at a distance.

How to do it, step by step

  1. Read the bark before you react

    Frustrated puppies lean forward, wag loosely, whine and bounce at the end of the lead. Worried puppies lean back, lower their tail, lick their lips, raise the hair on their back or bark and then retreat. The plan below is the same, but a worried puppy needs more distance and more time.

  2. Find the distance where your puppy can still think

    Walk somewhere you can see dogs from far away, such as the edge of a park. Note how close you can be before your puppy stops taking treats or looking at you. Practise just outside that line, not at it.

  3. Dog appears, treats appear

    The moment your puppy notices another dog, say “Top!” and feed a small treat, then another, while the dog is in view. When the other dog has gone, the treats stop. Your puppy learns that seeing a dog is a cue to check in with you.

  4. Curve, turn and leave

    When a dog comes towards you on a narrow path, walk in a wide curve, step behind a parked car or turn round with a cheerful “This way!”. Leaving is not failing: it stops your puppy practising the barking.

  5. Keep hellos short and with the right dogs

    Let your puppy greet only calm, friendly adult dogs whose owners agree. Allow three seconds of sniffing, then call your puppy away and reward. Most dogs you pass should be ones you simply walk by.

  6. Plan quiet days after busy ones

    Puppies need lots of sleep, and a stressful walk can leave them on edge for a while. After a busy outing, give your puppy a calm day with sniffing in the garden or a quiet street and plenty of naps.

Does your grown dog bark or lunge at dogs?

With a grown dog the barking has often been practised for months or years, and some dogs lunge or snap on the lead. That needs a slower plan, careful management and often a behaviour professional. The page for grown dogs explains what to do and when to get help.

What early experiences can and cannot do

Puppies learn very early what the world is like. A review of the research on socialisation found that dogs who were well socialised as puppies were less likely to show behaviour problems as adults, including fearfulness and aggression, and that socialisation should start early and continue into adulthood (Howell, King and Bennett 2015). For your puppy, that means calm, well-chosen meetings with other dogs now are worth more than lots of wild ones.

The same review is honest about the gaps. The evidence on puppy classes is mixed: one study found that attending puppy classes lowered the risk of aggression towards unfamiliar people, while another found little difference from a control group. Nobody yet knows exactly how much socialisation is enough (Howell, King and Bennett 2015). Good quality matters more than quantity: a puppy that is overwhelmed in a chaotic class learns little that helps.

How you react to the barking matters as well. Jerking the lead, shouting or spraying water can stop one bark, but a review found that aversive methods can harm a dog’s physical and mental health, and that there is no evidence they work better than rewards (Ziv 2017). A puppy that is unsure about other dogs and then gets a fright each time one appears has every reason to bark more.

Frustration or fear: quick signs

  • Frustration: forward weight, high wagging tail, whining between barks, pulling towards the other dog and calming down quickly once it can sniff.
  • Fear: weight back, tail low or tucked, ears flat, lip licking, trying to hide or getting behind you, barking and then backing away.
  • Mixed: some puppies switch from one to the other within seconds, especially with big or fast dogs. Treat mixed signals as fear and add distance.
  • Overtired: barking at everything late in the day. Shorter walks and more naps help more than training.

Common mistakes with puppies

  • Letting your puppy run up to every dog. It learns that dogs mean wild play, and barks when it can’t reach them.
  • Forcing a worried puppy to “say hello”. Being held in place near a scary dog makes the next meeting worse.
  • Dog parks and busy off-lead areas too early. One bad experience can stay with a young puppy.
  • Keeping the lead tight “just in case”. A tight lead tells your puppy something is wrong. Hold it loosely and add distance instead.

Frequently asked questions

Why does my puppy bark at big dogs but not small ones?

Big dogs move and sound differently and can be scary up close. Give your puppy more space around large dogs and reward it for looking at them from a distance where it stays relaxed.

Should my puppy say hello to every dog we meet?

No, most dogs should be ones your puppy simply walks past. Greet only calm, friendly dogs whose owners agree, keep it to a few seconds and call your puppy away with a treat.

Is my puppy barking at dogs because it wants to play?

Often, yes: frustrated barking usually comes with a wagging tail, whining and pulling forward. It still needs work, because a puppy that always expects to play will keep barking at dogs it can’t reach.

Can I pick up my puppy when a strange dog comes close?

Yes, if your puppy is small and frightened and the other dog is off lead, picking it up can keep it safe. Then turn away calmly and walk on rather than holding it up for the other dog to sniff.

Do puppy classes help with barking at other dogs?

A good one can: small groups, calm play and time-outs when puppies get too wild. The research on puppy classes is mixed, so choose one that keeps play gentle and lets shy puppies watch first.

My 5-month-old puppy suddenly barks at dogs: is that normal?

Yes, many puppies become more vocal around this age as they grow in confidence or meet new worries. Go back to more distance and more rewards for calm looking, and see a vet if anything else has changed too.

Should I tell my puppy off for barking at a dog?

No, a scolding adds stress and can make other dogs look even more worrying. Add distance, reward calm looking and leave if you need to.
