Dogs held in shelters for extended periods face significant welfare deterioration without structured enrichment programs, and evidence-based enrichment reduces behavioral problems and improves adoptability.
The shelter environment imposes chronic stress on dogs from novelty, unpredictability, noise, and loss of familiar social bonds. Dogs under prolonged stress develop behavioral changes including increased reactivity, reduced food intake, and stereotypic behaviors that paradoxically reduce their adoptability. Enrichment programs that provide play sessions, basic training, social contact with humans and other dogs, and mental stimulation through food puzzles actively counter this behavioral deterioration and serve both welfare and adoption success goals.
