While overall vision appears to be unaffected in advanced stages, a
dog may have problems visualizing
near objects, for example, food dropped on the floor.
The fearful behaviors in neutered
dogs included: responses to loud noises, when first exposed to unfamiliar situations, when approached directly by an unfamiliar child, when barked at, or growled at, by an unfamiliar
dog, or even when approached by another
dog of similar or larger size, when encountering strange or unfamiliar
objects on or
near the sidewalk, when encountering windblown
objects, when examined by a veterinarian, or when having their nails clipped.
