difference between a cocker spaniel and springer spaniel
English Springer Spaniel The English Springer Spaniel is similar to the English Cocker Spaniel and at first glance the only major difference is the latter's smaller size. However English Springers also tend to have shorter, and higher-set ears than English Cockers. In addition Springers also tend to have a longer muzzle; their eyes are not as prominent, and the coat is less abundant.[5] The major differences between the Welsh Springer and the English Springer are that the Welsh have more limited colours and tend to be slightly smaller.
Bull Terrier The Bull Terrier is a breed of dog in the terrier family. There is also a miniature version of this breed which is officially known as the Miniature Bull Terrier.
Pit bull The term pit bull is often used loosely to describe dogs with similar physical characteristics, and the morphological (physical) variation amongst "bully breed" dogs makes it difficult for anyone, even experts, to visually identify them as distinct from "non-pit bulls".[7][8][9] While mixed breed dogs are often labeled as "pit bulls" if they have certain physical characteristics such as a square shaped head or bulky body type,[10] visual identification of mixed breed dogs is not recommended by the scholarly community.[7]
American Bulldog The American Bulldog is a breed of utility dog. There are two specific types of American Bulldog, Standard and Classic; additionally, there are also mixes of the two types.
