The cocker spaniel is defined as a breed by its beautiful head and soft, intelligent eye expression. Developed as an upland game gun dog, it is compact and powerful with smooth, laid-back, laid-in shoulders, and a strong rear that allow it to move freely in the field and swim well in water. The smallest of the sporting spaniels, today’s cocker continues to exhibit the heart, stamina, and drive for field work, the grace and beauty that sparkles in the breed ring, together with an affectionate disposition that have made it among the most popular companion dogs for more than 60 years. The cocker spaniel comes in three varieties, based on color: black; parti (two or more solid colors, one of which must be white); and A.S.C.O.B. (Any Solid Color Other than Black).
