The English Springer Spaniel is a dog breed traditionally used for flushing and retrieving game, but due to their excellent sense of smell, they are also used as sniffers or detection dogs. Besides sniffing out explosives, the English Springer Spaniel can accustom its nose to the scent of bumblebee nests and blood. The typical Spaniel is eager to please, friendly, highly trainable, and willing to obey its owners. They are also known to stick to their favorite person as much as possible, thus gaining them the nickname 'velcro dog.' A Spaniel's exceptional stamina and willingness to work make them an excellent choice for search-and-rescue operations.
