Just like the rest of the body, the brain is affected by the aging process. Damage to the brain’s cells can lead to changes in your dog’s behavior and alertness.

It's important to remember that aging is a natural part of your dog's life. Half of all dogs 8 years and older will show some signs of brain aging, and as your dog ages, he may begin to act differently. Thanks to advances in medicine and pet nutrition, the right dog food and veterinary advice can help limit the effects of brain aging and maintain your dog’s activity level.

What causes my dog’s brain to age?

Aging takes a toll on a dog's entire body, including his brain. In recent years, scientists have made great strides in understanding the aging process. Today, many experts agree that aging is primarily caused by unstable oxygen molecules called free radicals. As the brain ages, free radicals cause damage to the cells. Although some free radicals may be caused by the effects of environmental conditions, the majority are produced by the body’s own metabolism.

The aging process attacks all body systems and organs in a dog, including the brain. The result is a loss of brain function, and often, the appearance of behavioral changes that were not present in a dog’s younger years.

Why is the brain susceptible?

Older, compromised mitochondria produce less energy and more highly toxic free radicals

Little can be done to stop free radicals from being produced. Antioxidants, vitamins and minerals have been found to counteract the damage caused by free radicals and may help maintain normal behavior for a long and healthy life.

Is my dog showing signs of brain aging?

Changes in brain function occur very slowly. The first thing you’ll notice may be small differences in behavior, such as increased sleeping, lack of energy or irritability. You may not notice these changes until they start to interfere with your dog’s everyday life. The following signs are commonly used by veterinarians in the diagnosis of brain aging. If any of these signs are affecting your dog, discuss them with your veterinarian.

Treatment: The importance of nutrition

To keep your dog acting young and healthy, proper nutrition is important. As your dog ages, continue to feed him foods rich in antioxidants and essential nutrients to keep him active and alert. Older dogs can continue to have a high quality of life and the food your dog eats plays an important role in his overall health and well-being. Balanced nutrition is an essential part of an active, healthy lifestyle. For accurate diagnosis and treatment options, always consult your veterinarian and ask them to recommend the best food for your dog’s brain health.
