Companion Dog Enrichment Science Evidence Base

The evidence base for canine environmental enrichment is growing, providing guidance for effective welfare enhancement.

Key Facts

Scent enrichment has the strongest evidence base for improving canine welfare outcomes
Social enrichment through appropriate dog-dog interaction reduces cortisol and increases play
Novel object presentation provides cognitive stimulation with individual variation in preference
Forced interaction with disliked enrichment causes stress rather than welfare benefit

Welfare Considerations

Enrichment is most effective when it matches individual dog preferences and motivations rather than being imposed uniformly. Evidence-based enrichment programmes consider scent, social, cognitive, and physical dimensions. Monitoring dog responses to enrichment allows individual optimisation rather than generic provision.

What You Can Do

Prioritise nose work and scent games as evidence-based welfare enrichment for dogs
Assess individual dog preferences in enrichment rather than assuming universal enjoyment
Rotate enrichment items to maintain novelty and sustained engagement
