With a massive body, broad skull and head of generally square appearance, is the largest dog breed in terms of mass. Although the Irish Wolfhound and Danish are higher, are not as robust.
The body is large, with great depth and breadth, especially between the legs, causing it to be well spaced. The AKC standard height (per their website) for this breed is 30 inches (76 cm) at the withers for males and 27.5 inches (70 cm) (minimum) at the withers for females. A typical male can weigh 150-250 kg (68-110 kg), a typical male can weigh 120-200 pounds (54-91 kg).
Coat Colour Standard
The standard specifies the hair should be short and tight (albeit with long-haired hounds, called "Fluffies" is occasionally seen) and the color is apricot-fawn, fawn silver, brown or dark fawn brindle, always with black on the muzzle, ears and nose and around the eyes.
The colors of the layer mastiff described differently by different kennel clubs, but they are essentially fawn or apricot, or colors as a base for black tabby. The black mask should occur in all cases. The female is usually a light color "silver", but can vary up to a golden yellow. The apricot can be of a reddish color to a deep, rich red. The tracks ideally should be strong, and even the clean lines, but actually can be light, irregular, irregular, weak or confused. Pied Mastiffs rarely occur. Other non-standard colors: brindle, blue and chocolate form. Some Mastiffs have a gradient caused by the heavy dark hair and around the shelter or mainly on the back and shoulders. Brindle is dominant to solid color. Apricot is dominant to fawn, but the domain may be incomplete. Most color defects are recessive, even if the black Mastiff is very rare in that you can determine if a mutation is recessive or dominant.
The highest weight ever recorded for a dog, 343 pounds (156 kg) was an English Mastiff named Zorba England Aicama La Susa, despite requests for large dogs exist.According the 1989 edition of the Guinness Book of Records In March 1989, when he was seven, Zorba was 35 inches (89 cm) at the shoulder and was 8.25 meters (251 cm) from tip of nose to tip of tail, the size of a little ass. After 2000, the Guinness Book of World Records have stopped accepting records of animals larger or heavier.
