The breed comes in a variety of sizes from medium to large, with the medium-sized one (seen here) called a “Pocket Bully” a term that just gives me the newbie jeebies all on its own.
The XL is the largest of four types of American Bully: standard, pocket, classic and XL. Strong enough to overpower an adult, the American bully XL can weigh more than nine stone (60kg).
