Evidence-based enrichment for dogs improves welfare through cognitive engagement, physical activity, and expression of natural behaviors — but not all enrichment is equally beneficial.
Enrichment science for companion dogs has advanced considerably beyond the notion that exercise and affection alone are sufficient. Dogs have complex cognitive needs — for problem-solving, sensory exploration, social engagement, and expression of species-specific behaviors like sniffing and foraging — that require deliberate, varied enrichment provision. Research consistently shows that dogs with access to appropriate cognitive and sensory enrichment show lower anxiety, fewer behavior problems, and higher positive welfare indicators. Translating this science into daily practice is one of the most accessible welfare improvements available to dog owners.
