Want to live a longer, healthier human life? Dog brains might hold key information for longevity.

Key Points:
- The Dog Aging Project studies over 50,000 dogs to advance research on aging in both canines and humans, collecting data on diet, exercise, blood samples, and brain MRIs to understand aging-related diseases that affect both species.
- Dogs age faster than humans and share similar environments, making them ideal subjects to bridge the gap between mouse models and human trials in aging research, with data publicly available and used in over 50 scientific studies.
- Researchers have found that social living and exercise reduce disease risk and cognitive decline in dogs, with tests assessing physical and mental fitness to identify signs of dementia similar to human Alzheimer's.
- Brain examinations of deceased dogs reveal structural and pathological similarities to human dementia, including beta amyloid plaques and brain shrinkage, supporting the relevance of canine models for Alzheimer's research.
- The project is testing longevity drugs like rapamycin in clinical trials to extend dogs' healthy lifespan, with biotech startups like Loyal developing preventive aging treatments for dogs that could inform human aging therapies.
