The Small Portuguese Hound is known by several names that reflect its Portuguese heritage and hunting function. The official registered name recognized by major kennel clubs worldwide is the Portuguese Podengo Pequeno, with Pequeno meaning small in Portuguese. In its native country, the breed is simply called Podengo Pequeno or referred to as part of the broader Podengo Português family. The name Podengo itself derives from the Portuguese word for warren hound or rabbit hunter, directly referencing the breed's primary historical function.
Throughout Europe, particularly in countries where the Fédération Cynologique Internationale standard applies, the breed is classified under the Portuguese Warren Hound designation, which encompasses all three size varieties of the Podengo. In Germany and other German-speaking countries, the breed may be referred to using translations of its Portuguese name. The breed has also been called the Portuguese Rabbit Dog in some historical texts, emphasizing its exceptional rabbit hunting abilities.
The Small Portuguese Hound designation has gained popularity among English-speaking enthusiasts who prefer a more descriptive common name over the Portuguese terminology. This alternate name clearly conveys both the breed's size and country of origin, making it accessible to those unfamiliar with Portuguese dog nomenclature. Some breed publications and informal contexts also use shortened versions such as PPP for Portuguese Podengo Pequeno or simply Pequeno when the context makes the breed clear.
In American kennel club circles, the breed achieved official recognition under the Portuguese Podengo Pequeno name, separate from its medium and large counterparts which are recognized as Portuguese Podengo. This distinction reflects the American approach of treating the smallest variety as a distinct breed for registration and show purposes. The United Kennel Club and Fédération Cynologique Internationale, however, recognize all three sizes under the single Portuguese Podengo breed standard, treating them as size varieties rather than separate breeds.
Historically, before standardized breed names became established, these dogs were known simply as rabbit dogs or ratters in Portuguese coastal and rural communities. Sailors on Portuguese ships knew them as ship dogs or vermin catchers, roles they performed admirably during the Age of Exploration. The breed's association with famous Portuguese explorers like Vasco da Gama and Ferdinand Magellan has led some to informally call them explorer dogs, though this is not an official designation.
The breed's recognition journey has been relatively recent outside of Portugal. The Fédération Cynologique Internationale first recognized the breed definitively in 1954 under Standard Number 94, which covers all Portuguese Podengo varieties. The Kennel Club in the United Kingdom recognized the Pequeno variety in 2003, while the American Kennel Club granted full recognition in January 2013 after the breed spent time in the Miscellaneous Class beginning in 2011. This progression from regional working dog to internationally recognized breed has helped standardize naming conventions across different kennel organizations.
