Although a couple of the breed standards differ a bit, there are not many types of Pitbulls. Breed standards for the Pitbull differ just a bit depending on if the dog is registered with ADBA, UKC, ABKC, and AKC (for American Staffordshire Terriers who can also be dual registered as APBT in UKC).
Different Types of Pitbulls
The UKC Pitbull can come in any coat color except merle. Nose leather can also be any color. The UKC Pitbull ranges from 35 to 60 pounds and can be up to 20 inches at the shoulders for females, and 21 inches at the shoulders for males.
Height of the Pitbull is not defined in the ADBA American Pit Bull Terrier breed standard, however the weight of the dog can be between 30 and 75 pounds when conditioned. The ADBA recognizes all coat colors, including the red/rednose. Merle coat patterns are not seen in this type of Pitbull. The ABKC breed standard defines the APBT as a dog that is up to 21″ tall at the withers and anywhere between 30 and 65 lbs. The ABKC does not recognize merle as an APBT coat color pattern. Last but not least, the AKC type is commonly known as the Amstaff. The breed standard of the Amstaff is included because Amstaff can be dual registered in ADBA and/or UKC as American Pit Bull Terriers. The AKC does not define the weight of the Amstaff in the breed standards, however the height of males and females should range between 17″ and 19″ at the withers, depending on gender. Although all coat color patterns are accepted except merle, it is not common to see a Red Nose Amstaff.
