American Cocker Spaniels have historically been associated with certain inherited health conditions, most notably cataracts and hip disorders. Through the ongoing efforts of dedicated preservation breeders and research supported by the American Spaniel Club (ASC), significant progress has been made in reducing the incidence of hereditary eye disease. Responsible breeders have their breeding dogs examined annually by a board-certified veterinary ophthalmologist to monitor for cataracts and other inherited eye conditions before they are bred. These regular eye examinations, combined with careful pedigree selection, have greatly reduced the occurrence of many hereditary eye disorders within the breed. Hip health is also an important consideration, as hip dysplasia can occur in Cocker Spaniels. Reputable breeders screen their breeding dogs for hip abnormalities and register the results with the Orthopedic Foundation for Animals, helping ensure that only dogs with sound orthopedic health are included in responsible breeding programs. These health testing practices are an important part of preserving the long-term health, soundness, and quality of the American Cocker Spaniel.
