Will the dog's eyesight be affected by the weather?

Yes, for example, in foggy days, the visibility is reduced, and the dog's vision will also be affected by the fog.

Dogs have better eyesight than people in dim light. Dogs are natural carnivores and live by hunting, so they also have considerable vision in the dark. Dogs' eyes can see short-wavelength colors, so dogs can see more clearly than people at sunrise or sunset. But in the darkness without light, dogs can't see.

Dogs also have bigger corneas, which allow more light to enter their eyes, so it is easier to see things in dim light.

Dog's vision

Dogs have a very broad field of vision. The left and right visual field of one eye is 100- 125 degrees (only 90 degrees for people), the upper visual field is 50-70 degrees, the lower visual field is 30-60 degrees, and the binocular vision can reach 250 degrees.

It can clearly see the object in front of it. Because of the flexible rotation of dogs' heads, they can "see all directions with their eyes".
