Why Doesn’t My Dog Bark? Do I Need To Consult The Vet?

Some dogs are naturally less vocal than others. The lack of barking could be due to the dog’s breed, temperament, or personality. However, if a normally vocal dog suddenly stops barking, it could indicate a health or behavioral issue, and a vet consultation might be advisable.

Why Doesn't My Dog Bark

11 Common Reasons a Dog Doesn’t Bark

Breed Predisposition

Some breeds are less vocal than others. For instance, Basenjis don’t bark but produce a unique yodel-like sound called a “barroo.”


Some dogs are trained not to bark. Example: A neighbor might train their dog not to bark so as not to disturb the neighborhood, using positive reinforcement every time the dog remains silent when prompted.


Medical Issues

Illness or injury can prevent a dog from barking. A dog with laryngitis or a sore throat might remain silent to avoid discomfort.


Older dogs might bark less due to decreased energy or developing health issues. A senior dog that was once vocal might become quieter as they age.

Fear or Anxiety

A dog might not bark if they’re feeling fearful or anxious. For instance, a dog afraid of thunder might hide instead of barking during a storm.


Deaf dogs might not bark because they can’t hear the stimuli that would typically prompt a response. A deaf dog might not react to a doorbell or other dogs’ barking.



Dogs that have been well-socialized might not see many things as threats and, therefore, might not bark. A dog exposed to various sounds and experiences as a puppy might remain calm and silent in diverse situations.


A happy and content dog has fewer reasons to bark. A dog that’s well-fed, exercised, and loved might simply not feel the need to bark.

Lack of Stimulation

Dogs in environments with little to no stimuli might not bark. For example, a dog in a shelter kennel without much interaction or activity might become numb and quiet.

Lack of Stimulation


Some dogs have undergone debarking surgery, a controversial procedure where the vocal cords are altered to reduce or eliminate barking. A dog that’s had this surgery will produce a muted or raspy sound.

Environmental Factors

Dogs might not bark in new or unfamiliar environments where they’re unsure of their surroundings. A dog in a new home might be quieter as it assesses its new environment.

When to Consult a Vet if Your Dog Doesn’t Bark?

If your dog doesn’t bark, it’s important to consider their typical behavior, overall health, and any potential recent incidents. Here are several circumstances when it might be appropriate to consult a vet:

Sudden Change: If your dog was previously vocal and suddenly stops barking without reason, it’s worth consulting a vet.

Signs of Illness: If the lack of barking is accompanied by other symptoms like lethargy, coughing, difficulty swallowing, loss of appetite, or any behavioral changes, it’s essential to seek medical advice.

After Surgery or Medical Procedure: Sometimes, after surgeries or procedures, especially ones involving the throat, a dog might not bark. See a vet if the silence persists longer than expected or if there’s any distress.

Age-related Concerns: While some older dogs naturally become less vocal, a sudden cessation of barking in seniors could be related to health concerns like cognitive decline, hearing loss, or pain.

After Trauma: If a dog has recently experienced trauma, such as a car accident or significant fall, and stops barking, it could be due to pain or injury.

Behavioral Changes: If the lack of barking is accompanied by other significant behavioral changes, like increased aggression, fearfulness, or anxiety, it might be related to an underlying health or behavioral issue.

Choking or Breathing Difficulties: If the dog shows signs of choking, breathing difficulties, or any obstruction in the throat, seek immediate veterinary care.

Difficulty Eating or Drinking: If the dog has trouble eating or drinking or seems to have discomfort around the mouth or throat, it’s essential to consult a veterinarian.

Persistent Hoarseness or Raspy Sound: If the dog tries to bark and the sound is consistently hoarse or muted, it could indicate a problem with their vocal cords or respiratory system.

When to Consult a Vet if Your Dog Doesn’t Bark

When do Puppies usually start to Bark?

Is it normal for Old Dogs to Stop Barking?

Yes, it’s normal for older dogs to bark less or stop barking due to decreased energy, potential hearing loss, or other age-related health concerns.

Can I Train My Dog to Bark?

You can train your dog to bark on command using positive reinforcement techniques, just as you can train them to stop barking.
