What does this mean for a dog with this trait?

There is no cure for X-linked progressive retinal atrophy type 2. Support includes providing extra light in low-light conditions and leashing in unfamiliar places at night. Depending on the progression of the disease, dogs may require additional supervision.

Symptoms

Signs of x-linked progressive retinal atrophy type 2 typically appear within the first 2 months of life. Dogs may show signs of night blindness, like increased hesitation and trouble tracking objects in low-light conditions. Signs also include an especially reflective tapetum. As the condition progresses, it may lead to total blindness.
