Paula, 50, from Surrey would like her dog Tom to stop barking constantly. 


Unfortunately, it’s not always as simple as asking nicely. Barking can drive many dog guardians up the wall with frustration as they try to enjoy a quiet night in. 


Thankfully, it is something that you and your dog can overcome by working together and using some of the tips from Omni’s vets. 


In this article, Omni’s co-founder and Chief Vet Dr Guy Sandelowsky will tell you exactly how you should overcome your dog’s constant barking which is, most of the time, a response to fear or anxiety. 

Reasons Why Your Dog is Barking


Firstly, it is important to remember that barking is a completely normal behaviour that almost all dogs do. A dog who never barks is like a person who never talks; it suggests there is something not quite right with your dog! 


That said, a few breeds of dogs never bark (including Bernese mountain dogs and Great Danes, due to their lung size) - but for most, barking is a normal part of communication, alongside body language and facial expressions. 


On the flip side, though, a dog who barks constantly - like a person who talks constantly - may well be showing signs of underlying chronic anxiety. 


The best person to understand the underlying causes behind your dog’s barking is actually you, the guardian, as you spend the most time with them. 


Next time your dog starts barking, rather than getting frustrated with them, try and figure out what they are barking at. Follow their eyes and try to see what they are looking at, or think back to what happened when the barking started. 


Factors that commonly set dogs off barking are: 


  • Strangers: Dogs often bark at unfamiliar people approaching the house or walking by, as they perceive them as potential threats.
  • Other Dogs: Whether it's across the street, in the park, or on TV, many dogs bark at other dogs, either out of excitement, territoriality, or fear.
  • Doorbells or Knocking: The sound of a doorbell or someone knocking is a common trigger for barking, as it signals the arrival of a visitor. This could also simply be on the TV or in a video, but your dog thinks it’s your door! 
  • Squirrels or Small Animals: Many dogs have a strong prey drive and will bark at squirrels, birds, rabbits, or other small creatures they see outside.
  • Noises: Unexpected or loud noises, like fireworks, thunderstorms, car alarms, or construction sounds, often cause dogs to bark due to fear or anxiety.
  • Vehicles: Some dogs bark at moving vehicles, such as cars, bikes, or motorcycles, as they perceive them as fast-moving threats that may crash into you or them. (Remember - dogs don’t necessarily understand cars!) 
  • People Walking By: Dogs, especially those near windows or in fenced yards, may bark at people walking past their territory as a way to warn them to stay away.
  • Delivery People (Mail carriers, etc.): Dogs often bark at delivery people, such as mail carriers or couriers, because they perceive them as intruders into their territory. 
  • Other Pets: Dogs may bark at household pets like cats, especially during moments of excitement, play, or if they feel their territory is being invaded.
  • Loneliness or Boredom: When left alone for extended periods, dogs may bark excessively as a way of expressing loneliness, boredom, or separation anxiety.
  • Communication: Dogs can also bark because they need the toilet, a toy is stuck under the sofa, or because they are tired or in pain. If they are trying to let you know something, chances are they’ll start barking about it!  

Once you have identified the trigger that starts your dog barking, you need to be able to desensitise them to it. 

How to Desensitise Your Dog and Stop Them Barking 


This method involves gradually increasing your dog's exposure to the trigger (e.g., vacuum cleaners, fireworks or postmen) in a safe manner. 


To do this you start with doing only the first part of the trigger and rewarding them if they make no response to it. 


In the vacuum example, this would mean regularly starting the action of opening the cupboard or plugging in the vacuum (reaching a point just before there is a reaction) then rewarding the dog if they do not react. 


Gradually over time you should be able to get slightly further with the action with no response, such as starting to drive the vacuum around the room without the power on. 


The same technique can be used to reduce reactivity to fireworks: simply start playing firework noises very quietly for short periods then gradually increase your dog’s exposure. 


It is important to remember that this method requires your dog to be in a calm and safe environment and takes a lot of patience and practice with them. You cannot rush it, as your dog will not make the progress you both want! 


You could also try creating a ‘Quiet Cue’ with your dog. 

What Is a Quiet Cue, and How Do I Train My Dog to Be Quiet? 

A quiet cue is a sign you give your dog that they should be quiet.


To start training a quiet cue, you can utter a simple command - like “Quiet” - just after your dog has stopped barking. 


Many behaviourists and trainers will pair this with a “Bark!” or “Speak!” command which they use while the dog is barking. This helps to highlight the difference between “Bark” and “Quiet”, meaning the latter is followed more closely. 


After using the quiet cue, you can give them a treat for being quiet. 


With practice, you should be able to start saying the quiet cue during barking (or perhaps when barking is tapering off) and then rewarding your dog for being quiet after you have said “Quiet”. 


Again, this takes a while to train into your dog, but once your dog has learned their quiet cue, you should be able to use it in any situation, provided you have your dog’s attention! 


How Can I Distract My Dog and Stop Them Barking? 

Distracting your dog from their trigger can be another way to stop them from barking. 


For example, something much more interesting than whatever it is that is making them bark could be their favourite toy or a play session with their favourite person (you!). 


This can also reassure them that everything is alright and they do not need to worry or guard their territory from strange invaders - especially if they see that you are perfectly happy and not showing signs of frustration or worry. 


Should I Punish My Dog For Barking? 

No. As vets and dog guardians, we are big advocates for positive reinforcement rather than negative reinforcement


What that means is that we advocate for rewarding your dog for good behaviours, rather than punishing them for bad ones. 


It can be frustrating being a dog guardian, but - like being a parent to a human child - it is both a duty and a responsibility for you to raise your fur baby as well as you can and set them up for success in the future.


Not to mention the fact that punishing your dog when they are already anxious can just prove to them that they are right to be anxious and thereby further entrench the behaviour! 


Dogs generally do not understand why they are being punished, but they do understand rewards - especially the tasty kind. 


Can I Use Supplements to Reduce My Dog’s Anxiety?

Many dog parents report that calming supplements can make a difference with overall demeanour and behavioural responses. 


For example, Omni’s ‘Stress & Anxiety’ supplement contains safe, natural and effective compounds like L-tryptophan, Passionflower, and L-theanine in order to support your dog’s peace of mind. 

How Does L-Tryptophan Prevent My Dog From Barking? 

L-tryptophan is an essential amino acid that helps in the production of serotonin, a neurotransmitter that regulates mood, sleep, and feelings of well-being.


By increasing serotonin levels, L-tryptophan can promote relaxation, reduce anxiety, and help with aggression or excessive barking in dogs. It's often used to calm dogs in stressful situations like travel, thunderstorms, or separation anxiety.


By reinforcing calmness through serotonin production, Omni’s vets believe that their Stress & Anxiety supplement can help calm your dog down and prevent excessive barking. 

How Does Passionflower Prevent My Dog From Barking? 

Passionflower is a plant known for its sedative properties. It affects the GABA (gamma-aminobutyric acid) system in the brain, which helps reduce nervous activity and promotes relaxation.


It’s commonly used to help dogs manage anxiety, hyperactivity, and stress. Passionflower can be helpful for calming dogs in anxious situations, reducing fear-based behaviours, and improving sleep quality.

How Does L-Theanine Prevent My Dog From Barking? 

Like L-tryptophan, L-theanine is an amino acid, but this one is found in green tea and is the active ingredient that promotes relaxation without causing drowsiness. It increases dopamine and serotonin levels while enhancing GABA production, which all contribute to a calming effect.


L-theanine is used to reduce anxiety and promote a calm, focused demeanour in dogs, particularly in situations like loud noises, new environments, or general stress.

When to Contact a Vet

You should contact a vet if:

  • Your dog is barking lots without an obvious reason, such as one of the triggers listed above.
  • Barking is accompanied by other worrisome behaviours or symptoms like pain, weight loss, or loss of coordination. 
  • You’re concerned about your dog’s behaviour, but you’re unsure if it requires emergency care.

You may also wish to contact a local dog behaviourist - just be sure to check they are professionally qualified and have positive client reviews. 

If you’re worried about your dog’s health, it’s always best to get professional advice. Book a free consultation with our vet team at Omni for expert guidance on what could be causing your dog’s excessive panting and how to manage it.

Thoughts from Dr Guy MRCVS


As dog lovers and guardians, it’s natural to worry about our furry friends, especially when they display abnormal symptoms that can’t be easily explained. That’s why, when I founded Omni, I knew that I wanted to keep vet consultation free and accessible at the heart of the business. 


If you’re understandably worried about your dog, but you don’t think you need to take them to the vets urgently, I highly recommend getting some friendly, professional advice from one of our team.

FAQs

But aren’t dog’s carnivores?

Dogs are in fact nutritional omnivores as demonstrated by a robust scientific study published in the reputable journal Nature (1,2) in which it was shown that they have 30 copies of the AMY2B gene responsible for digesting plant-based foods.

They have also evolved relatively long intestines (21) (almost as long as humans) and relatively flat surfaces on their molars (31, 22) which they use for digesting and chewing a whole range of foods.

The common misconception that dogs are carnivores probably arises from the fact that they are classified in the order Carnivora but so are plenty of other species like bears, skunks, racoons who are omnivores and even the giant panda who thrives on a plant-based diet (20).

Is plant protein digestible to dogs?

Absolutely yes, studies which have looked at how much protein dogs can absorb from plant-based and fungi-based foods like soya and yeast demonstrated over 75% digestibility which is on par with meat-based foods (23, 24, 34, 35 & 25).

Both these protein sources also contain all 10 essential amino acids (36, 37) that dogs need to thrive.

Isn't there too much fibre in plant-based food?

The average amount of fibre in a commercial dog food diet is between 2-4%. omni’s plant-powered recipe has a fibre content of 3% which is on par with meat- based diets.

In our survey with over 200 dog owners, 100% reported that their dog’s stool consistency was either ‘normal’ or ‘perfect’ and there were no reports of any digestive upsets (data on file).

Can I mix omni with other meat-based diets?

We are proud that our recipes are nutritionally complete and so include everything your dog needs to thrive. This means omni can be fed as a sole ration. We also fully support a 'flexitarian approach' like meat free lunches or using omni as a mixer.

Every little helps to bring some of the health and environmental benefits of plant-power to meal times. Mixing omni with meat/fish will help to add variety into your dog’s diet whilst adding in healthy ingredients with a relatively low carbon footprint.

Can plant-based food provide the essential fatty acids dogs need?

All the essential fats and oils that dogs need, including omegas 3 and 6 are found in a variety of both meat and plant-based foods (31, 28).

omni’s recipe is rich in plant-based sources of these nutrients so your dog will get all the essentials they need.

I hear a lot about feeding raw meat, isn’t that better?

Feeding raw meat to dogs has become a very popular trend in recent years, but most vets will warn against this practise. This is because the cooking process is vital to help kill off dangerous bacteria like E coli, Salmonella and Campylobacter (9) that have necessitated several food recalls from the market and caused serious illness and even death in both dogs and their owners (40, 41, & 42).

There are also several worms and parasites that are only killed off when raw meat is cooked. Dogs are dogs, not wolves and thanks to their domestication over thousands of years, thankfully don’t need to hunt to get their grub nor do they need to eat raw meat, it's just not worth the risk.
