The Journal of the American Veterinary Medical Association
(JAVMA) published a series in 2010 of three studies showing that dogs
who ate foods with Omega-3 fatty acids experienced less pain associated
with osteoarthritis and had more mobility.
published in the Jan. 1, 2010 and March 1, 2010 JAVMA issues, include 274 dogs with osteoarthritis that took part at dozens
of privately owned veterinary clinics and two university veterinary clinics.
Dogs and cats see the world very differently than we do as humans. Their perception, senses and color awareness is quite different
from our own.
A simplified explanation is that our eyes contain cells called cones.
There are three different types of cones. Cones catch light and respond to color. The more cones contained in the eye,
the more colors one can see along with a greater degree of vibrancy and richness. Humans have three different types of cones
and in addition, have a great number of the cones themselves. It's the combination of these three cone types along with how
many actual cones exist, that allow us to see the full spectrum of color along with a high degree of intensity.
eyes contain cones, but only two types. Where humans see the rainbow spectrum as violet, indigo, blue, green, yellow, orange
and red, dogs see this same spectrum as dark blue, light blue, gray, light yellow, brownish-yellow, and dark gray. From this,
we can determine that dogs basically perceive the world in variations of blue, yellow and gray with no green to be enjoyed.
Cats eyes are believed to contain three types of cones like humans, but they are not believed to
have as many cones as we do. This results in them seeing colors such purple, blue, green and yellow but colors of red and
orange are most likely viewed as shades of gray and they do not see vibrant colors as we do.
