After a lesson, what your dog does in the next hour matters
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
We fuss over session length, treats and tone of voice — almost never over what happens straight afterwards. Yet a Hungarian experiment compared four ways of filling the hour that follows a lesson, and the gaps are clear. Our guidance on setting up the resting area is gathered in the dog bedding and habitat section.
Four groups, one hour, two retests
Kis, Szakadát, Gácsi and colleagues published an open-access study in Scientific Reports in 2017 combining electroencephalography and behaviour (see the study). In its second experiment, 53 adult family dogs learned unfamiliar commands, then spent an hour in one of four randomly assigned conditions: sleeping in the owner's parked car, walking on lead, learning yet more new commands, or playing with a Kong. They were retested straight away, then a week later.
- Sleep: 57.5% correct responses at baseline, 59.5% at immediate retest, 67.8% a week on.
- Lead walk: 49.2%, then 54.4%, then 61.1%.
- Kong play: 49.0%, then 43.9% — a drop —, then 63.1%.
- Second learning task: 55.9%, then 51.9%, then 56.5%: no gain at all.
A first point, often skipped over: no group improved significantly at the immediate retest. The gaps open up a week later.
The one group that gained nothing
Three groups out of four improved significantly at one week. The group that went straight into a second lesson was the only one still at its starting point seven days later (occasion by condition interaction: χ²(4) = 14.435; p = 0.006). And it really was learning of the same kind — more commands to memorise — that is, interference, not some neutral activity. The actionable message here is a negative one: what matters most is not what to do after a lesson, but what to avoid — stacking two learning tasks back to back.
The Kong group carries the second lesson. It went backwards at immediate retest, then overtook everyone a week later. A dog that seems to have forgotten everything by the end of a session has not necessarily learned badly: it may simply still be aroused.
What the study does not show
It does not show that you should put your dog to sleep so it remembers better. In this second experiment the Sleep group did not improve significantly at immediate retest, and the authors themselves note that this appears to contradict their first experiment — fifteen dogs, three separate three-hour sleep recordings, a clear gain afterwards (t(14) = 3.833; p = 0.002). Their explanation: the retention interval differs, an hour of rest not being three hours of sleep. Add artificial conditions — the dogs slept in a parked car, not in their own bed — groups of only 12 to 14 dogs, a single task, and funding partly from industry, which the authors declare.
A 2024 study from the same group complicates the picture further: the post-sleep gain appears only in dogs given the encouraging session second, after experiencing a sterner one — which looks less like an effect of tone than an effect of the contrast between the two.
What to take from it
- One thing at a time: do not chain two new tasks, even if the second waits until tomorrow. Our guidance on rewards is in our article on dog training treats.
- Quiet is enough: a calm walk produced the same profile as sleep. Nothing requires sending the dog to its bed.
- Judge a week later, not at the end of the session.
Frequently asked questions
Does a quiet bed help the dog recover?
It is consistent with these results without being proved by them. Rest quality depends mostly on placement: see our article on fragmented sleep and bed placement, and all our guides on the dog hub.
