[ THE DATA ]

Why Dogs Lose Their
Homes

Behavior is the single largest reason owners give for surrendering a dog, but housing, inability to care for the animal, and having too many pets — all addressable through policy, not veterinary medicine — add up to more than behavior alone.

Why Dogs Lose Their Homes Share of owner surrenders by stated reason, pooled across shelter-intake studies SOURCE: Systematic review and meta-analysis of dog surrender reasons across shelter-intake studies “Other/unspecified” covers smaller or study-specific categories (moving without a housing-specific reason, owner death, biting incidents, etc.). A separate 2025 Best Friends Animal Society analysis found housing alone was the single largest reason in that year's data, at 16%. jeremymsparks.com — August 2026 0% 15% 30% Behavior — Share of surrenders: 28% Housing / moving — Share of surrenders: 18% Unable to care — Share of surrenders: 16% Too many pets — Share of surrenders: 10% Financial — Share of surrenders: 6% Allergies — Share of surrenders: 5% Other / unspecified — Share of surrenders: 17% BehaviorHousing / movingUnable to careToo many petsFinancialAllergiesOther / unspecified

How this was made: these numbers were researched and drafted by an AI model with web search, from a single topic prompt, then reviewed by a person before publishing. Every figure should trace back to a source the model actually cited — if one looks wrong, it might be. A Sankey's flows are checked to balance before publishing, but that only catches arithmetic, not a bad source. Treat this the way you'd treat any single research pass: a strong starting point, not a peer-reviewed one.
