According to statistics developed and maintained by the Orthopedic Foundation for Animals (OFA) since 1985, adult Boykin Spaniels have an alarmingly high incidence rate (> 30%) of hip dysplasia, although the rate is declining in the past 7 years due to the emphasis placed by the Boykin Spaniel Foundation. Canine hip dysplasia is considered by scientists to be both hereditary and acquired (due to diet, too strenuous exercise, and spay/neuter status.)
The breed also has a susceptibility toward inherited heart disease, eye disease and patellar luxation. Skin and coat problems do exist and may be linked to thyroid or endocrine disorders; most, however, are due to mites and other vermin which are acquired as puppies when raised in unsanitary conditions. Elbow dysplasia, Cushing’s disease and hypothyroidism are known in the breed.
