Using pet dogs to spot household risks for memory and senses loss

Companion dogs: sentinels for multimorbidity of human neurocognitive-sensory aging and susceptibility to Alzheimer’s disease and related dementias

NIH-funded research University of Wisconsin-Madison · NIH-11311836

This project looks at whether health and exposure patterns in pet dogs can point to home-based chemical risks that speed up thinking and sensory decline in older adults.

What this research studies

Researchers will enroll companion dogs that live in people's homes and measure the dogs' exposures to common household neurotoxicants. They will test dogs for memory, smell, hearing, and vision changes and collect environmental samples from the home. By comparing exposures and outcomes in dogs and available human data, the team hopes to find shared risk patterns. Because dogs age faster than people, findings in dogs may reveal harmful home exposures sooner than waiting for human cases to appear.

Who could benefit from this research

Good fit: Ideal participants are people who own companion dogs and are willing to allow their pet and home environment to be sampled and evaluated, especially if they are concerned about age-related thinking or sensory changes.

Not a fit: People without pets or those whose cognitive or sensory problems are clearly due to non-environmental causes (for example, purely genetic conditions) are less likely to gain direct benefit from this study.

Why it matters

Potential benefit: If successful, this work could identify household chemicals linked to dementia and sensory aging, guiding prevention and safer home practices for older adults.

How similar studies have performed: Some prior studies have used pet dogs to learn about environmental exposures and aging, but using dogs specifically as sentinels for shared neurotoxicant risks tied to Alzheimer’s and sensory decline is relatively new.
