A study in Budapest found that sleep significantly improves dogs’ ability to retain newly learned cues. Can Sleep Improve Memory in Dogs?

Researchers at the Institute of Cognitive Neuroscience and Psychology at the Hungarian Academy of Sciences taught dogs novel cues, then tested how well the animals performed the same commands after different activities during a three-hour interval. Sleep appears to support memory consolidation in dogs much like in humans and other mammals, with studies showing that dogs perform better on newly learned commands after a post-training nap.

In experimental work from the Hungarian Academy of Sciences, dogs’ post-learning sleep was linked to memory consolidation and, in some paradigms, to improved later performance, while engaging in unrelated learning after training could impede consolidation compared with conditions without such interference.

The experiment measured performance directly: in one experiment with a longer post-training sleep interval, dogs showed performance improvements after sleep, but in the 1-hour sleep condition of the main command-learning study, performance between baseline and immediate retest did not significantly improve; longer-term gains were seen after subsequent night sleep.

Anna Kis, a researcher at the Institute of Cognitive Neuroscience and Psychology at the Hungarian Academy of Sciences, led the team that designed the sessions and compared outcomes across conditions. The design isolated the post-training interval—three hours in total—to see how different activities affected consolidation of the newly taught responses.

Effective techniques for teaching dogs new cues include using short, positive-reinforcement sessions of just a few minutes, where the dog is repeatedly rewarded with treats, praise, or play. What are some effective techniques for teaching dogs new cues can enhance learning. Dog trainers and behavior experts welcomed the finding as confirmation of what some trainers have long suspected. “Sleep definitely helps dogs process new information,” said Nicole Kohanski, a dog behavior expert and trainer with the Academy for Dog Trainers, summarizing the practical implication in plain terms.

Celebrity trainer Jessica Jacobson added a reminder about training balance: “People often forget that mental exercise is just as important for dogs as physical exercise.” Her comment underscores that how a dog spends time after a lesson can matter as much as the teaching method itself.

The study’s contrast between passive rest and active interference—play or unrelated training—produced clear behavioral differences in short-term retention. Those differences suggest that activity immediately after learning can disrupt consolidation, while sleep appears to stabilize the new associations. During sleep after learning, dogs show changes in EEG activity during both non-REM and REM sleep that are related to later performance on the task; specific spectral changes reported include altered delta, beta, and alpha activity, with some REM delta and beta measures correlating with better performance.

Researchers framed the work as part of a broader effort to understand memory processes in domestic dogs and to translate laboratory findings into practical guidance for trainers. Related analyses and reporting on sleep and memory in dogs appear in outlets such as Dvm360 and in scientific discussions including material indexed by Nature, which explore how sleep influences consolidation across species.

For trainers and owners, the immediate takeaway is straightforward: allowing a brief nap after introducing a new cue may improve early retention, while filling the post-training period with other activities could undermine it. The study’s controlled comparison between napping and active interference produced the clearest signal in the animals’ subsequent performance.

The research was carried out in Budapest by the Institute of Cognitive Neuroscience and Psychology at the Hungarian Academy of Sciences. Its findings contribute to practical discussions about the timing and structure of short training sessions for companion dogs.
