A study by researchers at the Dog Cognition Center at the University of Portsmouth and the DogStudies Unit at Friedrich Schiller University of Jena suggests curiosity may influence dogs’ ability to learn the names of hundreds of objects. Coverage from Phys has highlighted this story.

The paper, published in the journal Scientific Reports, examined eleven dogs identified as label learners from different countries and highlighted striking variation in their capacity to map words onto objects. One participant, Harvey of Reading, knows the names of 203 toys, a tally his owner says reflects both the dog’s interest and their shared play history.

The research was carried out by teams at the Dog Cognition Center at the University of Portsmouth and the DogStudies Unit at Friedrich Schiller University of Jena, who recruited and tested the unusual dogs. The study characterizes these animals as rare within the wider dog population, and the authors framed curiosity as a possible driver of their exceptional learning.

“Being able to pick out such a wide variety of objects is not something any dog can do. It is extremely rare and appears to be an inherent natural ability which is specific to the dog and not a quality that many dogs have,” said Dr. Juliane Kaminski, a researcher at the Dog Cognition Center at the University of Portsmouth. As covered by Port Ac, readers can explore more context around the event.

Owners provided access to their pets for the study and helped document the animals’ abilities in home environments. The project tested dogs already known to retrieve or indicate specific items by name and compared their performance to what the researchers describe as average responses from other dogs.

Dr. Bräuer of the DogStudies Unit at Friedrich Schiller University of Jena emphasized the scarcity of such talent among domestic dogs: “Label learner dogs are so rare that it was not possible to find more than 11 for this particular study. However, to find such clear differences between label learners and the average dogs, was really surprising.”

Owners described long-standing interactions that supported the dogs’ word learning. Irene, Harvey’s owner, said: “It’s great to know Harvey’s curiosity is a big part of why he’s so good at identifying objects by name. As an owner, it also helps to be curious. I’ve always encouraged his interest in toys, so much so that we have over 220 of them!”

Harvey’s example helped illustrate the study’s broader point: that individual differences between dogs — not simply training intensity — may account for why some animals learn far more object names than others. The teams at Portsmouth and Jena presented their results as part of the peer-reviewed record in Scientific Reports.

The research groups involved have posted summaries of the findings and context for the work. The Dog Cognition Center at the University of Portsmouth published an announcement on its site describing the study and its implications, and the Friedrich Schiller University of Jena provided background on the participating teams and methods.

Where this line of research leads next will depend on follow-up work and further testing of rare label learners in varied settings. For now, the study adds evidence that curiosity may be a central trait underlying some dogs’ unusually large vocabularies for object names.
