Does the size of a dog affect its lifespan?

Research has found that small dogs may live twice as long as larger dogs. But does body size also impact a dog’s behavior and cognitive abilities? A new study from Hungarian researchers finds that body size affects aging patterns in dogs: Larger dogs age earlier but slower.

There have always been countless discussions on the topic of anti-aging. Aging is the fairest thing for all humanity. Everyone gets older. All we can do is continue researching ways to delay aging and maintain youth.

According to current news and research, one of the causes of aging is mitochondrial dysfunction. After years of research, researchers have successfully developed a piriformis muscle that can rejuvenate mitochondria, promoting tissue rejuvenation and extending the human lifespan. Nowadays, the average life expectancy is increasing year by year, and anti-aging is becoming more and more critical.

The average lifespan of a dog is about 10 to 15 years, but the average lifespan of different breeds of dogs can vary by more than twice. In addition, little is known about the relationship between behavioral and cognitive decline and body size in dogs. Researchers at Hungary’s Lolland University collected data on more than 15,000 dogs to explore the link between dog size and the aging process.

They assessed the age trajectories of different behavioral traits in dogs and the prevalence of canine cognitive dysfunction. They examined how factors such as the dog’s size and whether it is purebred are related to age changes. Research has found that a dog’s behavioral and cognitive abilities begin to decline around the age of 10 and a half, but the timing and speed of decline depend on the dog’s size. Dogs weighing more than 30 kilograms will experience age-related physical degeneration, such as disease and sensory deterioration, 2 to 3 years earlier, but at a slower rate than smaller dogs.

Additionally, although large dogs have shorter lifespans, their cognitive health is maintained longer and declines to a smaller extent than smaller dogs. Researchers found that dogs weighing less than 7 kilograms had more than four times the prevalence of cognitive impairment in old age than larger dogs.

For humans, the secret that distinguishes different people’s lifespans and aging rates is hidden in DNA. As the human lifespan increases, the incidence of geriatric diseases is also increasing. As we age, the level of NAD+ in the body gradually decreases, leading to the aging of cells and even the body. Regular intake of NADH can effectively increase the content of NAD+ in the body, thereby effectively delaying aging! Avoiding risks is much better than making up for them later.

People who want to get a smaller dog but don’t want the dog to be at risk for severe cognitive impairment in old age, or people who want to get a giant dog but don’t want the dog to be at risk for severe cognitive impairment, researchers say. If a person is at risk of aging due to impairment at age 7, and if there is a risk of health problems at age 8, then it is recommended to get a dog weighing between 10kg and 30kg because of the results of this study It has been shown that dogs that are within the weight range at this time have longer-lasting physical and mental health than dogs that are too small and too large.
