Plain-English summary
A study found that primary cataracts were diagnosed in 14.96% of single-colored English Cocker Spaniels and 5.51% of multicolored ones. This means that if you have a single-colored English Cocker Spaniel, there's a higher chance they might develop cataracts, which can affect their vision. The research looked at the eye health of over 1,200 dogs and found varying rates of cataracts among closely related dogs, but no clear pattern based on color or sex. If you're concerned about your dog's eye health, it's a good idea to discuss cataract screening with your veterinarian.

Abstract
OBJECTIVE: Two pedigrees from the German English Cocker Spaniel population are presented to illustrate the familial occurrence of primary cataract (CAT) in single- and multicolored English Cocker Spaniels. The aim was to characterize similarities and differences in the prevalence and formation of CAT in these separately bred color variants of English Cocker Spaniels. MATERIALS: The study was based on the veterinary records for presumed inherited eye diseases of 1232 English Cocker Spaniels which were provided by the German panel of the European Eye Scheme for diagnosis of inherited eye diseases in animals (DOK, <http://www.dok-vet.de>). Data included information on 615 single-colored and 617 multicolored English Cocker Spaniels. RESULTS: CAT was diagnosed in 92 (14.96%) of the single-colored and 34 (5.51%) of the multicolored English Cocker Spaniels. The pedigree of the single-colored English Cocker Spaniels included 40 ophthalmologically examined dogs with 18 unaffected and 22 affected dogs. The pedigree of the multicolored English Cocker Spaniels contained 16 ophthalmologically examined dogs with 11 unaffected and five affected dogs. CONCLUSIONS: In both color variants of the English Cocker Spaniels different forms of primary CAT with respect to location within the lens occurred among close relatives. Appearance of CAT was very heterogeneous without obvious sex differences. The sample pedigrees do not support the assumption of familial segregation of specific forms of primary CAT in English Cocker Spaniels.
