The World Records Authority is proud to officially recognise a truly unique display of focus, patience, and incredible skill. Border Collie Leonard Lee, accompanied by his owner Teresa Hanula of the USA, has set the official record for the Most Books Balanced by a Canine — a feat certified at one of the world’s most storied literary landmarks.

This extraordinary milestone was officially validated during a visit to Bertrand Bookshop in Lisbon, Portugal — the world’s oldest operating bookshop, established in 1732. The choice of location was itself a statement: a record-breaking act of canine intelligence and training, witnessed in a place that has stood as a monument to human knowledge for nearly three centuries.

The World Records Authority commends Teresa’s dedication to nurturing Leonard’s extraordinary talent and fostering such a strong, cooperative bond. Their achievement now joins the roster of prestigious international records maintained by the Authority, celebrating the remarkable potential that patient, dedicated training can unlock in our four-legged companions.
