To best define the ADBA and UKC standards it is necessary to highlight the difference between the two: as they are both common to have vigor, tenacity and power, but at the same time they are very different because the first association aims at work and the second to the exhibition.


  • The ADBA tends to push the character qualities of the American Pitbull Terrier as high as possible: aggressiveness, competitive spirit and temperament; and physical such as: resisting fatigue and allowing the dog to continue to fight even in extreme and unfavorable situations, which makes it a suitable dog for combat. Physically these dogs are leaner than those of the UKC to improve their performance. We are talking about the standard one that until recently (and unfortunately still today) was used to grow dogs suitable for clandestine fights, as they are agile, powerful and irrepressible.


  • The UKC thinks of the Pitbull with massive tonnage and head called a “brick”, in fact the dog raised with UKC standard has a bigger bone than one of the ADBA standard because over time the interest in aggression has become lost compared to its origins, in fact it is not forgotten, though it also goes towards aesthetics. All this is the result of years of selection to get a dog of greater size but with a level of aggressiveness practically zero, if well-behaved, compared to the first pitbull with “aggressive” characters, deriving from the terrier, which were much more accentuated.





The American Pitbull Terrier in ADBA standard having to perform competitive activities has an elongated musculature, which allows rapid shots, leaps and jumps.
The UKC standard specimens are endowed with even more imposing, massive muscular masses, but characterized by short fibers more suited to efforts than at competitive level as this subject has nothing to do with fatigue, work.

The ADBA standard wants the weight of the Pitbulls to go from 14 kg to 24 kg. This is because there must be a weighted balance between weight and power to guarantee its agility.
The UKC reaches 27kg but accepts even larger subjects that keep the measurements in proportion. Today, in fact, pit bulls are allowed up to 33kg.


Finally we can summarize the two standards in:

  • the “only practical” one, its standard (ADBA) does not aim at aesthetics, but wants to give the dog the physical and psychological condition that allows it to work and play sports at levels even beyond competition.
  • the “middle way”, its standard (UKC) points to a smoothing of the character in order to grow the harmless dog, thus aiming at improving the character but also the morphology
