Look for GANA (Goldendoodle Association of North America) membership as a starting quality indicator. Request OFA hip, CAER eye, PRA DNA (for the Miniature Poodle parent), cardiac evaluation (Golden parent), and patella evaluation documentation. Verify OFA numbers independently. Understand the generational designation of any litter (F1, F1B, F2, multigen) and what it implies for coat type and temperament predictability. Avoid any breeder who cannot provide complete documentation or who offers immediate availability without a wait list.
