Older Dogs Who Sleep Badly May Have Dementia

Doggie dementia is a worrisome reality for many senior dogs. Research has found that by 11 or 12 years of age, 28% of dogs had mild and 10% had severe cognitive impairment. By the time the dogs reached age 15, the risk had risen to 68% for mild and 35% for severe cognitive impairment. A 2022 study found the odds of canine cognitive dysfunction increased by 52% with each year of age.
