Animal shelters receive hundreds of thousands of surrendered pets annually, and the welfare of animals during shelter stays, and their outcomes at rehoming or euthanasia, varies enormously across facilities.
Shelter animal welfare varies dramatically between facilities and is strongly influenced by design, staffing, and enrichment provision. Shelter environments - with unfamiliar noise, smells, reduced social contact, and restricted exercise - cause measurable stress in dogs and cats that increases with stay length. Stressed dogs develop behavioural problems that reduce rehoming success, creating a welfare spiral. Foster programmes that place animals in temporary homes dramatically improve welfare for anxious individuals. Welfare-positive sheltering requires consistent human interaction, adequate exercise, veterinary care, and enrichment. Realistic length-of-stay limits coupled with high-quality foster networks deliver the best welfare outcomes.
