# Difference Between Staffordshire Bull Terrier, Pitbull and Amstaff > Not the same dog: 11-17 kg against 25-30, 2 FCI-recognised standards and one that is not. How to tell them apart, explained by a breeder. Complete guide to distinguish the three breeds **In brief:** [Staffordshire Bull Terrier](/en/), American Pit Bull Terrier and American Staffordshire Terrier are three distinct breeds, often confused with each other. The **Staffy** is the smallest (max 17 kg), the **Amstaff** is the largest and most muscular (up to 35 kg), while the **Pit Bull** (APBT) is not recognized by the FCI. ## Why Are These Breeds Confused? The confusion between **Staffordshire Bull Terrier**, **American Pit Bull Terrier** and **American Staffordshire Terrier** is extremely common, not only among laypeople but also in the media and sometimes in institutions. This confusion has concrete consequences: poorly written laws, unjustified prejudices and difficulties for owners. All three breeds descend from the same stock: the "Bull and Terrier" dogs of 19th century England, crosses between Bulldogs and various Terriers. They therefore share a common genetic heritage and some similar morphological characteristics: broad head, powerful jaw, muscular body. The media tend to use the generic term "Pitbull" to indicate any "bull" type dog, regardless of the actual breed. When a molosser-type dog is involved in an incident, the breed is rarely correctly identified, fueling generalized stereotypes. ## Historical Origins: A Common Ancestor ### 19th Century England: Bull and Terrier In the 19th century, animal fights were popular in England. The **Bull and Terrier** were born from crosses between Bulldogs (strength, grip) and Terriers (agility, tenacity). These dogs were used for "bull-baiting" and later, after the 1835 ban, for dog fights. ### Staffordshire Bull Terrier: The British Breed The **Staffordshire Bull Terrier** developed in the Staffordshire region of England. In 1935 it was officially recognized by the British Kennel Club. The FCI recognizes the Staffordshire Bull Terrier with **standard n. 76**, in Group 3 (Terriers), Section 3 (Bull type Terriers). ### American Breeds: Pit Bull and Amstaff **American Pit Bull Terrier (APBT):** Recognized by the UKC (United Kennel Club) in 1898 and by the ADBA. The APBT is **NOT recognized by the FCI** or the AKC. **American Staffordshire Terrier:** In 1936, the AKC recognized a "show" version of American Pit Bulls with the name "Staffordshire Terrier", later renamed "American Staffordshire Terrier" in 1972. The FCI recognizes it with **standard n. 286**. ## Physical Comparison: Table of Differences | Characteristic | Staffordshire Bull Terrier | American Pit Bull Terrier | American Staffordshire Terrier | | **Height males** | 35.5 - 40.5 cm | 45 - 53 cm | 46 - 48 cm | | **Height females** | 35.5 - 40.5 cm | 43 - 50 cm | 43 - 46 cm | | **Weight males** | 12.7 - 17 kg | 15 - 27 kg | 25 - 35 kg | | **Weight females** | 11 - 15.4 kg | 13 - 23 kg | 20 - 30 kg | | **FCI Recognition** | ✅ Standard n. 76 | ❌ Not recognized | ✅ Standard n. 286 | | **Country of origin** | Great Britain | United States | United States | ### How to Distinguish Them by Sight **The Staffordshire Bull Terrier** is the smallest and most compact.
