The English Springer Spaniel is a breed of gun dog traditionally used for flushing and retrieving game. It is an affectionate, excitable breed with an average lifespan of twelve to fourteen years. The English Springer Spaniel is a medium sized compact dog. Its coat is moderately long with feathering on the legs and tail. It is a well proportioned, balanced dog with a gentle expression and a friendly wagging tail. This breed represents perhaps the greatest divergence between working and show lines of any breed of dog. A field-bred dog and a show-bred dog appear to be different breeds, but are registered together.
