It can help keep weight in check, support hips and joints, and make mealtime easier on a sensitive belly. If you want food that truly fits an older dog’s changing needs, the right formula can make daily life feel smoother, healthier, and a lot happier.

Purina Pro Plan Senior Sensitive, Salmon

Purina Pro Plan Senior Sensitive Skin and Stomach with salmon and rice is the one I reach for when a dog has a delicate belly or itchy skin.
