... which is why it's important to pay attention to colour for trainin
g routines
and choosing toys.
Originally, scientists thought dogs could only see in black and
whi
te. It’s
now been proven that our four-legged companions are able to experience
colour.
To prove this theory, Italian researchers created a measurable way to assess
colour vision in animals using
a modified version of the Ishihara’s Test (used
to determine colour blindness in humans). What was discovered is that a
dog’s range of colour vision would be similar to yours and mine IF we were
affected by red/green colour blindness. The Ishihara’s Test for humans uses
numbers, disguised in a circle of red and green dots.
People with red/green colour blindness can't see the green
W in the first
circle. Th
ey might also have problems se
eing the green

in the second
circle.

So remember to choose your dog toys with colour in min
d.
Stick to blue instead of red since dogs
do have the capacity to see some blu
e
shades. A red toy is going to be hard to
distinguish from the
grass if it's lying
on the ground in the bac
kyard.
In addition, if you're outside,
avoid red clothing and shoes for training since it will be harder for
your dog to see your body movements against the green grass. Dogs also function more
accurately w
ith agili
ty training when the equipment is painted in colours they can easily see.
For dogs, the scientists used images
of
cats (animated frames) instead of numbers, and according
to the study's lead author, Dr
Marcello
Siniscalchi, the findings have a bearing on how you train
your dog, especially when trying to improve thei
r ability to pay attention.
Dogs see a simpler palette than we do. Where we can see dozens of variations between hues,
dogs can only see shades of blue, yellow, and some shades of gray. A dog's colour vision is
limited because they have only two types of cones,compared with three types in human eyes.
Dogs would see a rainbow as dark brownish yellow to light yellow, grays, and light blue to dark
blue. They c
an’t
see red, orange, or purple (violet).

Coupled with a limitation of
colour
vision, dogs are also very nearsighted. In the following chart,
compare our average
20/20 vision on the left, to a dog's average 20
/75 vision on the right.
The term 20/20 refers to the clarity and sharpness of human vision at a distance of 20 feet.
Below, the picture on the left shows how we would experience this moment. On the
right is the same scene depicting how
our d
og would see it.

As a Level II trainer with one of the leading North American
pet organizations, I log over 800 hours per year teaching people
how to train their companion animals. My classes range from
puppy level to advanced, including trick training, therapy
partnering, and private instruction.
Interspecies communication is the underlying principal of my
philosophy so that people and their dogs can better understand
one another to achieve a more productive and harmonious
partnership.
