Spaniel is a family of dog types rather than a single breed. The name traces back to an old word for Spanish, and these dogs were developed to flush game birds from cover and, in many lines, retrieve them. The group includes Cockers, Springers, Cavaliers and curly-coated water spaniels, and shelters often use the label for dogs with spaniel looks and uncertain ancestry.
Most adoptable spaniels are small to medium, with feathered ears, soft eyes and a silky or wavy coat. They're usually affectionate and sociable, with a busy nose and energy to match. Those traits fit Thornton's leashed lake and trail walks, though a coat that picks up burrs and mud needs regular brushing, and the ears need regular checks. How much of each depends on the dog's mix.
