What is the most common cause of inherited cataracts in dogs?

Inherited cataracts in dogs are predominantly the result of genetic factors. This means that certain breeds or individual dogs have a genetic predisposition that influences the development of cataracts. Inherited cataracts can vary between breeds, with certain breeds having a higher incidence due to specific genetic mutations or hereditary patterns. This genetic basis for cataracts is important for breeders to be aware of, as it can help inform breeding choices to minimize the risk of passing on these traits.

Trauma is a potential cause of cataracts but is not typically classified as an inherited condition; similarly, inflammatory conditions can lead to cataract formation but are acquired rather than inherited. Nutritional factors can affect overall eye health and may contribute to the development of cataracts but do not play a direct role in inherited cataract formation. Thus, when discussing inherited cataracts, genetic factors are clearly the most significant contributors.
