Wikimedia Commons classifies this historical US photograph as PD-US. PITVU relies on that explicit repository classification, not a licence from its uploader or the dog’s age alone. The photographer and exact first publication are not supplied; 1903 appears in the caption and repository date field, not an independently established exposure date. K84m97 is the uploader, not an established original photographer. Commons warns that public-domain status outside the United States can differ; universal worldwide clearance is not asserted. Full caption and original bytes are retained.
Exact named1936 caption, retained source-specific date/weight/owner/breeder. No accepted parent edges, photographs, inferred sex or birth locality.
