Under their breed standard, Cocker Spaniels should have “flat, silky coats to the touch that should never be wiry or wavy, nor should their coat be too curly or profuse” and their front and back legs as well as their bodies should be well-feathered. Some Cockers have a slight wave in their coats and although very rare, dogs can have very curly coats too which is thought to be a throwback to their water spaniel lineage.
