Dogs have a greater field of vision than humans. This enables them to see things to the rear and sides. The amount of overlap (shaded area) will determine how well the animal can judge distances.

A human has a field of vision of about 100 degrees.

A whippet’s field of vision is about 200 degrees.

Dogs that have been bred to look more like us, such as the King Charles Spaniel, with forward-facing eyes, have a reduced field of vision.

Long-coated breeds with hair that hangs over their eyes will have their field of vision greatly reduced. It is best to clip it or tie it back so that they can see properly.
