Are Dogs With Different Colored Eyes Deaf? There is no confirmed link between heterochromia and deafness in dogs. Rather, researchers think that the piebald or merle color gene influences both deafness and heterochromia, so dogs that carry those color genes may be more likely to exhibit both heterochromia and deafness.
Can heterochromia affect eyesight?
It can appear in someone with no family history of heterochromia. In most cases, it’s a benign condition not caused by an eye disease, nor does it affect vision. So it doesn’t require any type of treatment or diagnosis.
