The canine sand maze: an appetitive spatial memory paradigm sensitive to age-related change in dogs.
A sandbox with one buried treat cleanly separates young and old dogs’ spatial memory.
01Research in Context
What this study did
Lancioni et al. (2011) built a big sandbox for dogs. They buried food in one spot.
Young and old dogs had to remember where the snack was. The team timed how fast each dog found it.
No shocks, no loud noises—just sand, smell, and a hungry dog.
What they found
Young dogs sprinted to the treat. Old dogs took longer and dug in the wrong places more often.
The maze showed clear age gaps in spatial memory.
How this fits with other research
Lemons et al. (2015) also used food rewards with dogs. They showed that pairing the target odor with extra food makes the dogs’ sniffing harder to disrupt. Both studies prove dogs work happily for food in lab tests.
Peiris et al. (2022) sounds like a warning. When the clicker stopped leading to food, the dogs quit working. E’s maze never broke the food link, so performance stayed solid. The two papers together say: keep the payoff coming.
Willner (2008) tweaked question style to lower false scores in humans. E did the same for dogs by switching from tricky mazes to a simple sand hunt. Both remind us: test design, not the learner, decides what we measure.
Why it matters
You now have a quick, kind way to spot memory loss in dogs. The sand maze takes minutes, needs no shocks, and gives clear numbers. If you work with service dogs or pets, you can track aging and show owners hard data. Try it next time a senior dog seems “forgetful.”

03Original abstract
Aged dogs exhibit a spectrum of cognitive abilities including a syndrome similar to Alzheimer's disease. A major impediment to research so far has been the lack of a quick and accurate test of visuospatial memory appropriate for community-based animals. We therefore report on the development and validation of the Canine Sand Maze. A 4.5-m-diameter circular pool was filled with a sand and powdered food reward mix to a depth of 10 cm. Dogs were given 4 habituation and 16 learning trials which alternated a food reward being half (control trials) or fully-buried (acquisition trials) in a fixed location. After a 90-min break, a probe trial was conducted. Cognitively normal, aged (> 8 years, n = 11) and young (1-4 years, n = 11), breed-matched dogs were compared. After correction for differences in control trials, average probe times were 2.97 and 10.81 s for young and aged dogs, respectively. In the probe trial, both groups spent significantly more time in the target quadrant but there was a trend for young dogs to cross a 1 m(2) annulus zone around the buried reward more frequently (2.6 times) than aged dogs (1.5 times). Test-retest reliability in a subset of young dogs (n = 5) was high. On the basis of these findings, the Canine Sand Maze is presented as a quick, sensitive and nonaversive tool for assessing spatial learning and reference memory in dogs.
