The American Neo Bull is a large hybrid dog created in the United States. Breeders in the 1980s crossed different types of Bulldogs with different types of Mastiffs in search of a guard and family dog that had the Mastiff’s characteristic wrinkled face and gentle demeanor. The American Neo Bull was the result of breeding American Bulldogs and Neopolitan Mastiffs. This loyal and affectionate dog thrives on attention, daily exercise, and plenty of room to run and play indoors and out. While this active dog needs regular activity, he’ll also enjoy lazing around the yard on a nice day with his family.

American Neo Bull Breed History

The American Neo Bull is a hybrid breed made by crossing American Bulldogs and Neopolitan Mastiffs. The breed can also be called American Bandogge Mastiff, which is a term that refers to the offspring of any type of Bulldog bred with any type of Mastiff. The American Neo Bull originates in the 1980s, where two different breeders crossed different Mastiffs and Bulldogs together throughout several generations. They were bred to retain the wrinkle look and gentle attitude of the Mastiff, and attempts were made to breed out known health conditions. Today, an American Neo Bull can be 50% American Bulldog and 50% Neopolitan Mastiff, but often, those percentages will vary depending on the breeding program they have come from. The American Bulldog was brought over to the United States during the colonial period from Great Britain, where it was used to bait bears, bulls, and buffaloes. It survived throughout the ages on southern farms, where it caught pigs and cattle. Modern American Bulldogs are descended from these farm dogs of Alabama and Georgia. By the 1980s, popularity of these dogs grew as they became known as great family and guard dogs, although they are still not recognized by the AKC. The Neopolitan Mastiffs descend from the great Molossus breed, a dog used by the Romans for battle and arena combat. Later, Romans used the Neopolitan Mastiff to guard their homes and farms, a job they are still used for by modern Italians. Neopolitan Mastiffs were recognized by the AKC in 2004 as part of the working group.

American Neo Bull Breed Appearance

The American Neo Bull is a large to giant sized dog, who has inherited many traits of his parents, the American Bulldog and the Neopolitan Mastiff. Like the mastiff, this breed is thick-boned. It is heavily muscled like the Bulldog. This breed boasts a large and deep chest, and a thick, muscular neck atop wide shoulders. Strong and sturdy legs provide a graceful, lion-like gait, typical for Mastiffs. Despite his size, this dog displays great agility. The face has Mastiff style wrinkles, with gold to dark brown eyes and ears that drop to the sides that are sometimes cropped. A short snout ends in a wide nose with large nostrils. The straight tail of this breed is thickest at the base and tapers to the tip. The hair of the coat is short, dense and waterproof, and can range in texture from harsh to smooth. Coat colors can be solid or in combinations of black, light fawn, brown, blue, gray, brindle, and white. There can also be white markings.

American Neo Bull Breed Maintenance

The American Neo Bull has low grooming needs. His short and dense coat does not shed much, and a regular weekly brushing will keep it free of debris and looking great. To keep his coat clean, give him an occasional bath only when necessary. Pay special attention to the skin of his face, as those cute wrinkles can be prone to skin infections. Routinely clean the skin and face to remove any bacteria that could cause problems. Be sure to keep the nails trimmed and check the hair in between the pads for debris. Remember, your American Neo Bull carries a lot of weight and his feet can become irritated or injured more easily than other dogs.

American Neo Bull Activity Requirements

The American Neo Bull is often called a gentle giant, as he is known to be laid back, gentle, and affectionate. This loyal dog is devoted to his family, which can make him wary of strangers in his desire to protect them. While gentle with children, his size can make him accidentally step on or knock over small children. While playful and highly energetic, supervision may be needed. This dog does well with other household pets, so long as he is properly socialized at a young age. While very intelligent, American Neo Bulls can be difficult for first time owners to train. They need an experienced handler who can be firm, but not harsh, as they are sensitive to the tone of your voice. The Neo Bull needs to know who is in charge, but without unnecessary roughness. Patience is needed to train this large dog, but he loves to please his family, and will willingly participate in many different activities. This dog requires a lot of exercise, and is best matched with an active family.
