Boulonnais
The Boulonnais, also known as the "White Marble Horse", is a draft horse breed. It is known for its large but elegant appearance and is usually gray, although chestnut and black are also allowed by the French breed registry. Originally there were several sub-types, but they were crossbred until only one is seen today. The breed's origins trace to a period before the Crusades and, during the 17th century, Spanish Barb, Arabian, and Andalusian blood were added to create the modern type. During the early 1900s, the Boulonnais were imported in large numbers to the United States and were quite popular in France; however, the European population suffered severe decreases during 20th-century wars. The breed nearly became extinct following World War II, but rebounded in France in the 1970s as a popular breed for horse meat. Breed numbers remain low; it is estimated that fewer than 1,000 horses remain in Europe, mostly in France, with a few in other nations. Studies as early as 1983 indicated a danger of inbreeding within the Boulonnais population, and a 2009 report suggested that the breed should be a priority for conservation within France. The smallest type of Boulonnais was originally used to pull carts full of fresh fish from Boulogne to Paris, while the larger varieties performed heavy draft work, both on farms and in the cities. The Boulonnais was also crossbred to create and refine several other draft breeds.

What to Know Before Buying a Boulonnais
Finding a responsible Boulonnais breeder requires more than browsing classified ads or responding to social media posts. The USDA requires any breeder who sells horses commercially — especially those selling online or through third-party dealers — to hold a federal license and submit to regular inspections. A legitimate breeder should be willing to provide their USDA license number, invite you to visit their facility, and show you where the animals are housed and socialized.
Before committing to a purchase, ask the breeder for veterinary health records, vaccination documentation, and any genetic testing results relevant to the Boulonnais. Reputable breeders will also ask you questions in return — about your living situation, experience with animals, and ability to provide long-term care. A breeder who asks no questions and is eager to ship an animal immediately is a significant red flag.
Use the search tool below to check whether any USDA-licensed facilities breeding Boulonnaiss appear in our database. If they do, review their inspection history carefully. Look for patterns of violations, pay attention to severity levels, and compare their compliance grade with other breeders in the same state. This due diligence takes minutes and can save you from supporting a facility with documented animal welfare problems.
