Can Dog See Colors Just As We Do?
by Ransi Plick Website OwnerA
life in ‘black and white’, without those fluorescent colors is highly unimaginable
for and by the human beings. This is even so for the animals. Till now, the
world was obsessed with the belief that their pets such as dogs and cats are
totally colorblind. But in contrast to this, scientists and researchers have
come out with the experimental proofs that dogs could also view a wide range of
colors with their eyes, and their vision is not limited to blacks and whites.
Obviously, the range of vision in dogs is not
comparable to humans in terms of colors but just as normal human eyes could
differentiate between two distinct colored objects, similarly the dogs too have
the same capability.
Can Dogs View All The
Colors?
If
you talk about the vision of dogs, their natural ability to distinguish between
shades is highly limited. The color field of dogs consists mainly of shades
ranging from violets, blue and yellow. Every other color that humans could
decipher well, would lie in the same range for the dogs. For example, the red, green
and orange spectrum of the human would probably not be understood by the dogs
and would lie somewhere in between the blue and yellow spectrum for them.
The
reason for this is that similar to the humans, dogs eyes too contain the rods
and cone cells, which are responsible for providing vision and distinguish
objects based on their color, shape and size. While the eyes of human consist
more of cone cells, dogs consist of more rods and they also lack fovea. Fovea
is a small part of the eyes that consist of closely packed cone cells.
Due
to this differentiation between the eyes of dogs and humans, the human could
see a lot more colors as compared to the canines they rear, while the color
viewing capability of dogs may be limited. Their vision could also be
considered limited while viewing shapes of objects as they could not find accurate
details for the same. But this does not make the humans superior, as presence
of more of rod cells denote an extra vision in their eyes. Dogs have an
exceptional night vision and this is even helpful in tracking movements of
objects, even when it a slight one.
Does Limited Color Tracking Affect
Dogs?
Absolutely
not! Dogs need not note every distinct color that is recognized by the eyes of
humans. Though a red ball if lying on green grass could not be deciphered
distinct and would appear yellow on yellow, dogs could very accurately pick the
ball you throw. How? Well, instead of distinguishing the color of objects, the
eyes of dogs do track their movements and based on this, they could bring back
a thrown ball.
Many
of the pet owners who follow proper pet
grooming tips may be unaware of the fact. They tend to mix some kind of
food coloring such as red or orange in the dog kibbles they prepare and hope
that the dogs would find this interesting to eat. This probably would not turn
out to be an effective measure, as red or orange colored cookies and other food
items would only appear to be yellow in the eyes. Similarly, the fluorescent
clothes that you bring for your dogs are highly undistinguished and could be
limited to a particular spectrum.
Colors
could play a big role for humans, but for pets they hardly make any difference.
Therefore, it is not important for a dog to identify every color. Instead, the
owners should try to maintain proper eye hygiene for their pets, so that their
vision remains superb, especially at night and their eyes are not subjected to
any disorders.
