Early recognition of canine cognitive dysfunction and preventive lifestyle interventions from middle age onwards may slow progression and extend the period of good cognitive health.
Cognitive dysfunction prevention is an increasingly important focus as canine lifespan extends with veterinary advances. The analogy with human dementia research — where prevention is far more valuable than treatment — applies to dogs as well. Building cognitive reserve through lifelong learning, maintaining physical fitness and providing social engagement throughout life appears to delay clinical onset. The welfare benefit of extending the period of cognitive health is substantial — dogs with good cognitive function live fuller, more engaged, less anxious lives in their senior years.
