Dogs Don’t Just Remember Words: They Understand How to Use Their Toys

What if some dogs do far more than merely remember amusing names? A study conducted in Budapest shows that a few champions of canine vocabulary can also grasp how to use an unfamiliar toy. A fascinating discovery at the crossroads of language science, memory, and animal intelligence.

Seven exceptional dogs enabled observation of a rare form of verbal understanding

For several years, researchers at the Eötvös Loránd University have been tracking a small group of dogs capable of learning the names of dozens of toys. These animals, called Gifted Word Learner dogs, are not the norm in the canine world. But they offer a rare research ground to observe the limits of the cognition of a domestic companion.

In 2025, Claudia Fugazza‘s team crossed an intriguing threshold. Seven dogs were exposed to new toys during a week of play with their owners, without any schooling protocol or rote repetition. The idea seemed simple: assess whether they remembered objects. The result, however, proved far more destabilizing.

The dogs did not merely retain word-object associations. They demonstrated that they could extend a verbal label to a toy never seen before, not because it resembled another object, but because it served the same type of action. For animal cognition, the nuance is enormous.

The tested dogs linked unknown objects to their use rather than to their form

In children, this mechanism exists from a very young age. A cup remains a cup, whether it is plastic, glass, or ceramic. What matters is the shared use. Seeing a dog approach a comparable line of reasoning changes the usual scene. It is no longer merely about obedience; it represents a form of categorization.

In the study published by Current Biology, the dogs tested had to distinguish toys linked to two specific uses, such as pulling or fetching. Even when objects differed greatly in their shape, texture, or color, the correct choices exceeded chance. In other words, appearance did not dictate everything.

That is the point that most intrigues researchers. A dog can therefore build a mental bridge between visually distant objects, based on a common function. This is not language in the human sense yet, of course, but it is no longer mere parrot-like memory from a four-legged creature.

Vision, smell and sensory memory illuminate how dogs categorize a toy

This performance does not rely solely on vocabulary. Earlier work shows that dogs can be influenced by a spatial bias. Many first spot a position in space before attaching to the object itself. Those with better visual acuity, however, seem less trapped in this reflex.

Vision is only one piece of the puzzle. The dog also navigates with scent, texture, and accumulated play experience. Researchers describe a multisensory memory, able to assemble multiple cues at once. It is perhaps this sensorial intelligence that enables, when faced with an unfamiliar toy, to immediately recognize what can be done with it.

Daily play with humans sometimes suffices to yield abstract learning

That is probably the most captivating dimension of this discovery. The dogs were not trained as laboratory animals. They learned in a familiar setting, in contact with their humans, during ordinary play sessions. This spontaneous learning brings the experience closer to everyday life.

The figure is striking all the more since only seven dogs were tested, which invites caution. Yet the reach of the result goes beyond this small sample. It suggests that some dogs form practical concepts through social interaction, as if play becomes a discreet laboratory for understanding the world.

This line of research already attracts applied inquiry. Better understanding how a dog generalizes a function could influence canine education, assistance, or even certain search missions. And behind this mountain of plush toys, one question remains. How many animals understand more than we think, simply because we never ask them the right questions?
