In fact, different vision and even some dogs are more popular. For example, some dog breeds, such as Australian shepherd, husky and terrier, have different pupils. Therefore, among these varieties, heteropupil is regarded as a peculiar and precious feature.
Of course, pupillary ectopia may also be the manifestation of some health problems, such as congenital glaucoma and cataract. If the dog's heteromydia is accompanied by abnormal symptoms such as eye pain, tears and corneal opacity, seek medical attention in time.
In a word, heteropupil is not a defect, but a unique eye color. As long as the dog behaves normally, the abnormal pupil does not affect its life and health.
