Can extra weight weigh on your dog's brain?
Reported by Phys.org · October 16 at 3:00 AM · Summary by Pawdeck
Researchers at Oklahoma State University, led by student Alexandra Genualdi, studied golden retrievers using data from the Morris Animal Foundation Golden Retriever Lifetime Study. They found that obese dogs were more than twice as likely to develop several serious health problems, were less active, and showed more signs of cognitive decline with age. The work was presented at a 2026 American Physiological Society conference in Orlando.
Background
Obesity in dogs is linked to conditions such as arthritis, diabetes-related hormone disorders and ligament injuries, largely because extra weight strains joints and the body's metabolism. Veterinarians often assess cognitive decline in older dogs with owner questionnaires about disorientation, sleep changes and housetraining lapses.
Why it matters
Keeping a dog at a healthy weight may help protect its joints, activity level and mental sharpness as it gets older.
What you can do
Ask your veterinarian to check your dog's body condition score and set a realistic target weight. Plan gradual changes to diet, portions and daily activity together with the vet.
