nherited eye disorders are common in many purebreds. Some disorders can be predicted with genetic testing, but others can only be diagnosed with health testing, which will tell you if the dog has the disorder at a specific point in time.
Knowing if your dog is at risk for genetic eye disorders is relatively easy for purebreds, since some diseases are well known to exist within certain breeds. However, it’s much harder to determine if a mixed breed dog is at risk of a genetic eye disorder, since most owners don’t know the exact breeds that make up their mixed breed dog.
