Women, dogs, old age, obesity, people, and using the second to learn about the last

From David J. Waters, "Aging Research 2011: Exploring the Pet Dog Paradigm," 52 ILAR Journal 97 (2011).



"Female survival advantage is well documented in certain mammalian species, most notably humans ... where it translates into a greater likelihood that women will live to 100 years, outnumbering men by approximately 4:1."

"... dogs were twice as likely as males to achieve exceptional longevity. However, removal of ovaries during the first 4 years of life completely erased the female survival advantage."

"...the aging beagle provides a spectrum of cognition—from intact to selective losses in specific cognitive domains to a more global dysfunction that mimics the deficits seen in early Alzheimer’s disease in humans"

"Estimates indicate that 20-40% of the pet dog population is clinically obese."
