Purina Pro Plan Bright Mind Medium & Large Adult 7+ is a dry dog food formulated specifically for senior medium and large-breed dogs aged 7 years and older. The formula is designed to support cognitive health in ageing dogs, addressing one of the most under-recognised aspects of canine ageing — cognitive decline.

The formula uses enhanced botanical oils containing medium-chain triglycerides (MCTs) which provide an alternative energy source for the ageing brain. After age seven, a dog's brain becomes less efficient at processing the energy found in standard food, which is associated with reduced mental alertness. According to Pro Plan's research, dogs fed this formula show measurable improvements in mental alertness and sharpness within 30 days. Made with real chicken as the primary protein and designed for the maintenance nutritional needs of medium and large senior dogs.

Bright Mind is one of the more scientifically targeted senior dog formulas on the Australian market. Owners often report noticeable changes in their older dog's alertness, engagement and willingness to play after a few weeks of feeding — which for a senior dog owner can feel like getting a younger dog back.
