10,000 dogs needed for study of aging

SEATTLE, Washington - Can old dogs teach us new tricks? Scientists are looking for 10,000 pets for the largest-ever study of aging in canines. They hope to shed light on human longevity too.

The project will collect a pile of pooch data: vet records, DNA samples, gut microbes and information on food and walks. Five hundred dogs will test a pill that could slow the aging process.

"What we learn will potentially be good for dogs and has great potential to translate to human health," said project co-director Daniel Promislow of the University of Washington School of Medicine.
