THIS IS AWESOME! My favorite dog trainer and dog whisperer of all time has just released a free video online explaining how to eliminate 94% of all unwanted behavior in ANY dog. Her name is Krista Cantrell and I absolutely LOVE the way she teaches. Click on the video to watch. You'll be glad you did...

Dogs are said to have the ability to see spirits and other paranormal entities unseen by man. Vision is generally believed to be the least sensitive sense of a dog. Dogs are famed for their excellent senses but while they have superior hearing and scenting abilities, their vision is rather poor.

Have you ever wondered how dogs see? Dogs’ vision is different from ours in several respects. Before studies have been conducted on how dogs see, it was a common belief that dogs can see only whites and greys. Dogs can see colors as what was proven by various studies but unlike humans that have trichomatic vision, dogs are known to have dichromatic vision. While humans can see the whole spectrum, dogs can see only some colors in the spectrum. It would be impossible to ask dogs what colors they see but it is generally believed that dogs primarily see shades of yellow and blue. Dogs cannot distinguish red and orange as they do not have the cones that are sensitive to these colors.

Dogs may be poor at distinguishing colors but they sure can see better in the dark. This ability enables dogs to hunt and capture prey even in the night. Dogs can unerringly capture prey even in the dark because of their incredible night vision. Dogs make dependable guards not only because of their alert and protective nature but also because of this night time vision. Dogs have an excellent night vision because they can dilate their pupils more thereby letting in more light.

Dogs owe their incredible night vision to the a layer of reflective cells called tapetum lucidum, situated behind the retina that reflects back light and allows to see objects clearly even in dim light. Because of the way the eyes are situated; dogs have a well developed peripheral and wide angle vision. Dogs can detect the slightest movement even at a distance.

Dogs though have low visual acuity thus they would find focusing on the shape of an object difficult. These animals can detect movements at a distance but they would not be able to distinguish the shape of the moving object. An object that can be clearly seen by humans at 75 feet would only be distinguished clearly by the dog at 20 feet

Dogs see the world in a much different way as compared to how the world is seen by humans. Dogs have a rather inferior vision (as compared to our vision) but this kind of vision is just sufficient for their needs.
