Advance Mature is a dry kibble formulated for senior medium-breed dogs, using chicken and rice as the primary ingredients. The 20kg bag is designed around the changing nutritional demands of ageing dogs rather than simply repackaging a standard adult formula — it targets the specific health concerns that surface in a dog's later years.

The recipe addresses several key concerns in ageing medium-breed dogs: joint support to maintain mobility, brain health nutrients to support cognitive function, and controlled mineral levels to reduce the risk of lower urinary tract issues. Selected oils support skin and coat condition, which can deteriorate in older dogs. Chicken delivers the protein base; rice keeps the formula easily digestible.

Owners of senior medium-breed dogs often stay with Advance through the later years because the formula addresses ageing-specific concerns in one bag. The well-known chicken and rice base tends to be easy on sensitive digestions, which becomes more relevant as dogs age.
