Why Do Small Dogs Bark So Much?

Reasons Small Dogs Bark Too Much

Small Dog Syndrome

Some smaller dogs can develop an attitude called “Small Dog Syndrome.” This isn’t an actual syndrome, but a term used to describe certain behaviors. Because they are small, they might feel the need to act aggressively or dominantly to assert themselves, especially in the presence of larger dogs or humans. This behavior can manifest as excessive barking.

Small Dog Syndrome

Bred for Barking/Protection

Historically, some small breeds were purposely bred to alert owners to intruders or for protection. Despite their size, these dogs had a loud bark, which was desirable for alerting their owners. Over time, these genetic tendencies have persisted, leading some small dogs to bark more than others.

Lack of Training

Regardless of size, if a dog hasn’t been properly trained or socialized, it may use barking as its primary mode of communication. Small dogs, sometimes treated more leniently due to their size, might not receive the same discipline or training as larger breeds, leading to unchecked barking behavior.

Breed Temperament

Every dog breed has a distinct temperament. Some breeds, especially smaller ones, are naturally more vocal than others. For example, breeds like Chihuahuas, Dachshunds, and Yorkies are known for their spirited and sometimes vocal nature, which can result in frequent barking.

Breed Temperament

Fear or Anxiety

Small dogs may feel more vulnerable due to their size, leading them to bark at perceived threats, even if those threats are benign. This can be other animals, strangers, or unfamiliar sounds.

Attention Seeking

Sometimes, barking is a way for small dogs to get attention. If owners respond to their barking (even negatively), it reinforces the behavior.

Physical Needs

Like any dog, a small dog may bark to indicate that it’s hungry, thirsty, or needs to go outside.

Health Issues

Some medical issues, such as pain or cognitive dysfunction, can increase barking. Always consult a vet if you notice sudden changes in your dog’s behavior.

Environmental Stimuli

Small dogs can be sensitive to their surroundings. Loud noises, other animals, or even a gust of wind can trigger a barking episode.

Tips to Stop Small Dogs from Barking too much

Consistent Training

Establish a command like “quiet” or “enough.” Reward your dog when it stops barking upon hearing the command. Consistency is key; all family members should use the same command and approach.

Avoid Reinforcing the Behavior

Avoid giving attention, treats, or reinforcement when your dog barks for no reason. Wait until they’ve stopped barking before you acknowledge them.

Divert Attention

Use toys or initiate play when your dog starts to bark. This diverts their attention from barking to a more positive activity.


Expose your dog to various people, places, and other dogs regularly. The more accustomed they are to different stimuli, the less likely they are to bark in response.

Use Positive Reinforcement

Always reward quiet behavior. This can be with treats, praise, or attention, reinforcing that quiet brings good things.

Increase Physical Activity

Sometimes dogs bark due to pent-up energy. Regular walks, play sessions, or agility training can help them burn off energy and reduce barking.

Mental Stimulation

Engage your dog’s mind with puzzle toys, obedience training, or games. A mentally stimulated dog is less likely to bark excessively.

Set Boundaries

If your dog barks at people or other animals outside, limit their access to windows or doors where they might get triggered. Alternatively, use curtains or opaque films to obscure their view.


If your dog barks at specific stimuli (like the doorbell), desensitize your dog by exposing them to the stimulus at a low intensity and rewarding calm behavior. Gradually increase the intensity as they become more comfortable.

Consider Professional Help

If barking is persistent, consult a dog trainer or behaviorist who can provide personalized strategies and insights.

Anti-Barking Devices

There are devices like ultrasonic trainers that emit a sound in response to barking, which can deter the behavior. However, use them with caution and preferably under the guidance of a professional.

Health Check

Always rule out potential health issues that might be causing discomfort and leading to barking. A visit to the vet can provide clarity.

Are Small Dogs Breeds More Aggressive?

Small dog breeds are often perceived as more aggressive because they tend to be more reactive and vocal, possibly as compensatory behavior for their size. However, aggression is not limited to size, and individual dog temperament can vary widely within any breed. Proper training, socialization, and understanding of the specific needs of a breed can significantly influence a dog’s behavior.

Which Breeds Bark Less?

Certain breeds are known for being quieter or less prone to barking without cause. Breeds like the Basenji, Shiba Inu, and Whippet are often noted for their quieter nature. However, individual temperament, training, and environmental factors play significant roles, so exceptions can always exist within any breed.
