Water is the Most
Important Nutrient
Animals need about two
times more water than
food. Fresh, clean water always
should be available to pets. Left
standing, water goes stale and
loses its nutrients. Also, a water
bowl needs to be cleaned
daily to prevent germ buildup.
Color Vision in Dogs
Dogs are not color blind, but they
have poor color vision. In comparison
to humans, dogs not only see
fewer colors but also a more faded
version of the colors we see.
A dog’s eye contains more rod
shaped cells than cone cells. Fewer
cone cells are the reason why dogs
perceive colors lighter than they exist.
In addition to this, a dog’s eyes
contain only two of the three types
of cone shaped photoreceptors.
Thus, they see only certain colors
of the color spectrum and are said
to have dichromatic vision.

dog can see? Researchers state that
dogs can identify shades of grey,
selected shades of blue and shades
between brown to yellow on the
color spectrum. Dogs cannot distinguish
between reds and greens and
perceives them as shades of grey.
