Pets with sensitive stomachs often cycle through foods without lasting results. Digestive issues can show up as inconsistent appetite, loose stools, reduced energy or skin concerns. For older pets, those challenges can become even more noticeable as nutritional needs change with age. Pet parents searching for answers often turn to probiotics or supplements, but finding a complete food specifically designed for digestion can still feel limited.
Purina Pro Plan is expanding options with a new lineup built around digestive and immune support. The brand’s AdvantEdge formulas introduce a triple-action blend of prebiotics, probiotics and postbiotics, designed to support gut health while also addressing broader wellness needs. The launch includes adult digestive support and senior-focused nutrition for both dogs and cats, giving pet parents more targeted choices based on life stage and sensitivity.

Triple Action Digestive Support Designed for Dogs and Cats
Purina’s new AdvantEdge Adult Digestive Support+ formulas focus on microbiome balance using a three-part approach. The combination of prebiotics, probiotics and postbiotics supports digestion, nutrient absorption and immune function. Each formula also includes real protein as a primary ingredient, along with antioxidants to help support immune health. The recipes avoid artificial colors and flavors and are available for both dogs and cats.
Digestive health plays a major role in overall well-being. Research increasingly links gut balance to immune function, energy levels and even emotional behavior in pets. One recent report highlighted the connection between digestion and mood, noting that changes in the gut microbiome may influence how dogs respond to stress and environmental triggers. You can read more about that relationship in this article summarizing the Journal of the American Veterinary Medical Associationdog gut emotional well-being connection study.

Spectacular Support for Senior Dogs and Cats
For pets entering their senior years, the AdvantEdge Senior Support+ formulas take a broader approach. In addition to digestive health, these recipes target cognition, immune function and mobility. Senior dogs receive support for mental sharpness, joint health and weight maintenance. Senior cats benefit from nutrients designed to support longevity, immune strength and lean muscle maintenance.
Given how much of a pet’s immune system originates in the gastrointestinal tract, digestive support is a foundational part of overall health rather than a single-issue solution. The new formulas build on that concept by combining gut support with targeted life stage nutrition.
Some pet parents also complement food changes with add-ons designed to support digestion. Options like this Target Brutus Bone Broth Gut Health Support Vitamins and Supplements can be used to enhance palatability while introducing additional digestive support. Pairing a balanced diet with targeted toppers may help pets transition more comfortably when switching foods.
The new AdvantEdge line includes multiple bag sizes and is available for both dogs and cats. Adult digestive support recipes feature salmon-based formulas, while senior options include chicken-and-rice blends. The foods are available through pet specialty retailers and online shopping channels nationwide.
The launch reflects a growing focus on functional nutrition across the pet care industry. Instead of general formulas, brands are increasingly introducing foods tailored to specific needs, such as digestion, joint support or senior wellness. For pet parents navigating sensitive stomachs, targeted nutrition like this offers a more structured starting point without relying solely on supplements.
