This time around, the group recruited 10 GWL dogs and 21 non-GWL dogs, all border collies, since this the most common breed to fall into the GWL category. They compiled a list of eight toys: two labeled, two unlabeled, and four that were new to each dog.

There was a two-week period where owners familiarized the dogs with the toys once a day for at least 10 minutes. Each toy was presented separately. For the labeled toys, owners moved the toy while crouched on the floor, repeatedly naming the toy (“Look at the [toy name]! Here is the [toy name]”). They did not name the unlabeled toys. Owners devoted an equal amount of time to all the toys. Novel toys were excluded from the familiarization phase.
After that period, each dog participated in two trials lasting 90 seconds each. The dogs were provided free access to the toys (washed with soap to control for odor cues). In the first trial, owners entered first and placed the labeled and unlabeled toys, plus two of the novel ones, on the floor and stood at a distance, passive and ignoring the dogs as the latter explored the toys. After a five-minute break, the test was repeated with the other two novel toys. All tests were recorded remotely and the footage subsequently analyzed.
Human babies are known to pay more attention to named objects, and the authors thought the GWL dogs would show a similar response, but that’s not what happened. All the dogs, whether they were GWL dogs or not, strongly preferred the new toys, and there were no significant differences between the two groups of dogs in terms of how much time they spent playing with labeled vs. unlabeled. So just hearing the names of toys does not automatically increase a dog’s attention.
