The dogs stand 14 to 16 in (36 to 41 cm) at the withers and weigh 24 to 32 lb (11 to 15 kg) (male dogs are normally up to 6lb heavier).
Temperament:
Although individual differences in personality exist, common traits exist throughout the Staffords. Due to its breeding, the modern dog is known for its character of indomitable courage, high intelligence, and tenacity.
This, coupled with its affection for its friends (and children in particular), its off-duty quietness and trustworthy stability, make it a foremost all-purpose dog . It has been said that "No breed is more loving with its family"
The breed is naturally muscular and may appear intimidating; however, because of their natural fondness for people, most Staffords are temperamentally ill-suited for guard or attack-dog training.
The Staffordshire Bull Terrier appeared in the top 10 breeds most suitable for families and especially children in a report researched and published by Southampton University in 1996. Staffordshire Bull Terrier puppies are very easy to house train.
As with any breed, irresponsible breeding can cause the spread of hereditary genetic flaws. Tests are performed to screen for these conditions.
Two of the conditions that can be detected by DNA testing are L-2-hydroxyglutaric aciduria (L2HGA) and Hereditary Cataracts (HC). This testing need only be done once. There are another two conditions which can be checked by way of an ocular examination throughout the life of a breeding stud or brood-bitch to minimize the transfer & spread of these conditions. The first is distachiasis (commonly known as “double eyelash”) where eyelashes are misdirected and begin to rub against the eye, particularly the cornea, causing ocular surface damage. The second is Persistent Hyperplastic Primary Vitreous (or PHPV) which is a condition whereby the blood supply to the ocular lens fails to regress and fibrovascular tissue forms causing hazy vision.
The breed is known to be at risk from melanoma, often seen in the stomach area as Staffys love to sunbathe on their backs.
