Dogs in shelter environments face significant psychological stress that can be mitigated through evidence-based enrichment programmes, reducing length of stay and improving welfare.
Shelter stress is a genuine welfare harm that affects both the dogs' experience and their adoptability. Stressed dogs appear more reactive, bark more and show less affiliative behaviour toward prospective adopters, reducing adoption rates and prolonging kennel stay. Enrichment programmes that provide daily human interaction, training sessions, outdoor time and sensory variety transform both welfare outcomes and adoption success.
