Spaniel is a family of dog types rather than one breed. The name traces back to an old word for Spanish, and these dogs were developed to flush game birds and often retrieve them. The group runs from English Springers and Cockers to Boykins, water spaniels and toy Cavaliers, and a dog labeled spaniel is frequently a Cocker or Springer type or mix.
Most adoptable spaniels are small to medium, roughly 20 to 50 pounds, with long feathered ears, soft eyes and a silky or wavy coat. They're usually affectionate, sociable and eager to please, with a busy nose and real energy. Coats and ears need regular care, and size, energy and grooming needs vary with the mix, so get to know the dog in front of you.
