Reasons Why Your Dog Is Not Barking At Strangers

Medical Issues

Typically, when a dog is sick, it becomes inactive. Suppose your pup suffers from health issues that affect its ability to bark. It will not bark at any intruder; instead, it will isolate itself in a quiet and calm area of your house.

Lethargy, loss of appetite, disinterest in toys, and any form of socialization are possible signs that you would see in a sick dog. You will notice that your active dog will become passive.

This aloofness will make your pet distant from its environment, reducing the chance of barking at any stranger or other pet.

Furthermore, it is possible that too much barking has strained your pup’s voice. Assuming it abruptly stopped barking or appears to be straining to bark without producing any noise.

Suppose your pet has recently had surgery or a medical procedure or is recuperating; it could hamper its ability to bark.

However, suppose your pet suddenly stops barking. In this case, it likely indicates a health problem, and you must not hesitate to consult a veterinary doctor.

Breed Disposition And Personality

It is common knowledge that some breeds have quiet personalities that are not suited to excessive barking.

This does not exclude the chance that they will bark. Or expressing themselves in other ways, such as howling or whimpering. However, in general, these dogs do not bark very much.

While the breed’s temperament might play a factor, dogs have their personality traits. Some dogs are too relaxed or pleasant to bark, while others may dislike the sound of their barking.

A New Environment Could Be Why Your Dog Is Not Barking

Your silent dog may be afraid to bark because he was just adopted. It is especially true for dogs adopted from a shelter or rescue. More often than not, your pup will display its best behaviour in the days or weeks after its adoption.

If this is the case, as your dog grows more at ease in his new surroundings, he may begin to bark more. This scenario is akin to the new kid in school, who is shy and reserved. However, this changes when they familiarize themselves with their environment and new schoolmates.

However, in some cases, the reverse is the case. Some newly adopted dogs will hit the ground running to claim their territory and show dominance to their owners or other pets.


The previous owners of your pet have likely trained it not to bark loudly or even bark at all. Suppose this is the case, and you have no prior knowledge of your pup’s history. It is possible that its previous owners likely taught it to be a passive dog.

Although training still is the best method to teach your dog not to bark, the previous owners may have debarked your pup. Debarking a dog is a surgical operation that clips the vocal cords to lessen sound.

Physical Abuse

It is also possible that your pet suffered physical abuse at the hands of its previous owner anytime it barked. The abuse is likely to have traumatized your pup, which makes it fear it will face similar punishment if it barks.
