This is an amendment to the basic standard which a XL Bully is determined by its adult height. Males over 20″ – 23″ at the withers. Females over 19″ – 22″ at the withers.
Important to note that the XL Bully variety is simply taller than the Standard American Bully. XL Bully dogs share the same build, body type, and breed type as the Standard American Bully, and are expected to carry a heavily muscled, massive, bulky body type.
