Pro Plan Senior Dog Medium/Large Chicken. Complete Pet Food for Medium and Large Size Dogs Aged from 7 Onwards. A combination of key nutrients that helps to support healthy joints for your senior dog's active lifestyle. Around 7 years of age a dog's brain starts to lose its ability to use glucose for energy. Over time this change causes dogs' brains to become slower and you might start seeing changes in your dog's behaviour like memory loss reduced activity levels etc. OPTIAGE™ contains MCTs (medium chain triglycerides) from botanical oils that provide an alternative energy source to the brain which results in a more curious and responsive dog - see visible results within 30 days. The diet helps maintain dog's social interaction with their families thanks to improved brain function. OPTIAGE™ is made with highly digestible ingredients that are carefully selected to help support healthy ageing thanks to specific protein and fat levels adapted to mature dogs' needs.
