Get to know more about this unique breed’s history and care requirements.


The appearance of the Merle Pitbull, a unique and controversial breed, is characterized by its distinct color pattern and physical attributes. The Merle Pitbull, also known as the American Pit Bull Terrier, is typically medium-sized, with males weighing between 35-60 pounds and females between 30-50 pounds. While Pitbulls come in various colors, the merle pattern is not accepted in standard Pitbull color variations. This pattern features mottled patches of color and odd-colored eyes, making it stand out from other coat variations.

In addition to its unique color pattern, the Merle Pitbull has a short, smooth coat with a single layer. This breed’s physical attributes include a height range of 17-20 inches at the shoulder, with males weighing 35-65 pounds and females 30-50 pounds. Their single-layer coat may make them less resistant to colder temperatures, necessitating proper shelter or clothing during chilly weather. Overall, the Merle Pitbull’s appearance is visually striking and adds to the controversy surrounding this particular color variation within the breed.


With roots dating back to the late 1900s, the murky history of the Merle Pitbull breed unveils a tale of intentional breeding for the distinctive Merle coat pattern. The introduction of the Merle gene into Pitbull breeding is a relatively recent development, with its origins traced back to the United States.

Initially, the Merle coloration was permissible in breed standards, but its rarity was primarily due to associated health concerns. Breeders historically focused on the functionality of Pitbulls in activities like hunting, sports, tracking, and protection rather than their aesthetic appeal.

Following the outlawing of bloodsports, breeders began to place more emphasis on the visual characteristics of the breed, leading to the intentional breeding for the Merle coat pattern. However, controversy surrounds the reintroduction of the Merle gene due to the potential health risks associated with it.

This historical backdrop has contributed to the uniqueness and rarity of the Merle Pitbull breed in the present day.
