With a 25 to 35 cm, the Miniature Bull Terrier is a strong built, proportioned, with an elongated head, deep, whit an oval face.

The neck is powerful and long; the back is short and strong; the body, well rounded and with a wide ribcage; the thorax, wide from the withers to the sternum; the lower outline with a graceful upward curve. The tail is short, low inserted, narrowing toward the tip. The shoulders are strong, not heavy; heavy boned limbs, but not coarse; the forelegs are moderate in length; the hind legs, parallel, well developed and angled. The coat is short and straight; in white colored dogs, the white is pure; in colored dogs, the color should predominate over the white.
As the Miniature Bull Terrier itself, this breed is spreading as wildfire! The Bull Terrier’s small brother, the Miniature, bravely measures against the most capable guardian breeds, despite its fewer centimeters.
This relatively new breed is perhaps many people’s dream: an attractive Terrier breed, without the exaggerations that make the Standard Bull Terrier so singular. The Miniature Bull Terrier gets a “ten” for its perfect size, although it is maybe too small to have the guarding potential of its big brother. It is still a fabulous watch dog, adaptable to diverse lifestyles, active and alert, and a lot of fun. Children love the breed, and especially females are excellent family companions.
Don’t be fooled by the Word “miniature”: this is an active breed, with a lot of energy, who needs an owner with the same temper. Perfectly apt as a family dog, the Miniature Bull Terrier can live in a flat, if provided with enough walk/exercise time. It is said that females adapt to the city life better. 

Robust, brave and cheeky, the Miniature Bull Terrier is very confident and decided since it is a puppy. As other Bull type breeds, it is demanding and needs a patient and clever owner to handle the breed’s stubborn nature. 
A well bred Miniature Bull Terrier has been as healthy animal, with few growth problems. The puppy grows gradually until reaching adulthood, at which time it shouldn’t go over 35 cm to the withers. Due to the breed’s relative rarity and lack of public information, the interested party should devote more time to talking with breeders. The Mini Bull is a highly energetic companion, considerably demanding as far as exercise and training. Diet should be provided as prescribed by the breeder to satisfy the large energy demand, and help guarantee its growth.
What else can we ask for in such a size? Despite its size, the Miniature Bull Terrier is free of congenital problems that affect other miniature breeds. 
Little can we find about hereditary and congenital defects in the Miniature Bill Terrier, and the information authors have obtained suggests few problems. This is notable, since this is a breed made miniature, which has developed from a relatively small breeding base. However, it is true that its original breed, the Bull Terrier, doesn’t have too many hereditary problems either. Deafness should be watched in some breeding lines, as well as lack of tail incidence, and loin and umbilical hernias. Otherwise, it seems that the largest owner’s concern is protecting this small portion of high energy from its own fearlessness and many times its bold character – injuries, mostly cuts and broken bones are the most common health problem this breed’s owners will have to face. Hair care is minimal, but it needs a lot of exercise and training.
