Most people think of dogs as loyal companions who respond to basic commands like sit, stay, or come. These commands are usually taught through repetition, treats, and direct interaction. But new research suggests that a very small group of dogs can do something far more impressive. They can learn the names of objects simply by listening to humans talk, even when no one is speaking to them directly.
This surprising ability is something scientists have long associated with human toddlers. Young children often pick up words by overhearing conversations between adults. They are not always being taught on purpose. They listen quietly, observe what is happening, and slowly connect words with objects and actions. According to a new study, a rare group of dogs appears to use a very similar method.
The Dogs Who Learn Like Toddlers
The research was led by Shany Dror, a postdoctoral researcher at the Veterinary University in Vienna and Eötvös Loránd University in Budapest. Dror and her team found that some dogs can learn the names of new toys simply by overhearing their owners talk about them with someone else.
These dogs were not being trained. They were not rewarded with treats or praise during the conversation. They were just present in the room, quietly listening.
Dror explained that this kind of learning is known as learning by observation or eavesdropping. Until now, it was mostly seen in young children who are still developing language skills. Seeing this ability in dogs was both unexpected and exciting.
The researchers call these exceptional animals Gifted Word Learner dogs, or GWL dogs for short. These dogs are able to build large vocabularies without formal training, something most dogs never do.

Meet the Gifted Dogs
One of the most impressive dogs in the study is Basket, a seven year old female Border Collie. Basket knows the names of more than 200 toys. When her owner asks her to fetch a specific item, she can reliably choose the correct one from a large pile.
In some cases, Basket can even retrieve personal items when asked. This shows that she is not just memorizing sounds. She understands that words represent specific objects.
Another standout is Shira, a nine year old rescue dog who reportedly recognizes over 300 toy names. For comparison, many dogs only learn a handful of commands throughout their lives. These gifted dogs operate on an entirely different level.
Dror noted that watching dogs perform tasks once thought to be uniquely human is striking. It offers a new perspective on how complex and socially aware dogs truly are.
How Scientists Tested the Dogs
To understand how these dogs learn new words, researchers designed two experiments involving ten gifted dogs.
In the first experiment, owners briefly introduced two new toys to their dogs. After this short introduction, the owners stopped engaging with the dogs and began talking about the toys with another person. The dogs were nearby but were not part of the conversation.
After just eight minutes of overhearing the discussion, seven out of the ten dogs were able to correctly identify the new toys when asked. No extra instruction or training was given during that time.
This result showed that the dogs were not relying on direct teaching. Instead, they were learning by listening and making connections on their own.
The second experiment added another challenge. This time, the dogs were tested on their ability to recognize the name of a toy without being able to see it. Even with the toy out of sight, most of the dogs were still able to learn and remember the new word.
This suggests that these dogs form mental images of objects based on language alone. They were not just reacting to visual cues or tone of voice.

Why Most Dogs Cannot Do This
It is important to note that this ability is extremely rare. Most dogs do not learn words in this way. While dogs are generally excellent at reading human gestures, facial expressions, and emotions, only a small number seem capable of learning object names by overhearing conversations.
Dror emphasized that these gifted dogs should not be seen as typical. Earlier research already showed that dogs are highly skilled at understanding human communication. This new study simply shows how far that ability can go in exceptional cases.
Scientists believe that a mix of natural traits and life experiences may play a role. Some dogs may be born with a stronger sensitivity to human speech. Others may develop it through constant interaction with people who frequently name objects during daily life.
At this stage, researchers still do not know which factors matter most or how they interact.
What This Means for Understanding Intelligence
These gifted dogs provide a valuable opportunity for scientists to study how learning and communication work across species. By examining how dogs connect words with objects, researchers can gain insights into the basic building blocks of language.
Dror explained that while dogs are not learning language in the same way humans do, their abilities may reflect some of the mental skills that made human language possible in the first place.
The study builds on earlier work from the Genius Dog Challenge Research Project, led by experts at ELTE University. This ongoing project focuses on understanding how dogs learn and remember object names over time.
Researchers involved in the project are actively looking for more dogs who can identify at least ten toys by name. Expanding the group of gifted dogs will help scientists identify patterns and better understand how these rare abilities develop.

What Dog Owners Can Take Away
For most dog owners, this research does not mean their pet will suddenly start learning new words just by listening. However, it does highlight how closely dogs pay attention to human speech, even when we think they are not listening.
Dogs are constantly observing their environment and the people around them. In rare cases, that quiet attention leads to remarkable learning abilities.
This research also reinforces the idea that dogs are far more mentally complex than they often appear. While only a few may qualify as gifted word learners, all dogs benefit from rich social interaction and communication.
As scientists continue to explore how dogs think and learn, these exceptional animals may help reshape our understanding of intelligence, communication, and the deep bond between humans and their canine companions.
