Bringing Dog Vision in Focus

Veterinary ophthalmologists are often asked, "How well do animals see?" Visual function involves a combination of many factors, including: the field of view, depth perception, acuity, perception of motion, and color differentiation. All of these functions must then be integrated by the brain to produce useful vision. Although we are unable to ask our pets to read an eye chart, through comparative studies, it is possible to make some educated assumptions about their vision.

Most humans have the ability to see all the different colors of the electromagnetic spectrum, and consequently perceive all its' colors. Man's best friend is colorblind, but, fortunately, his survival does not depend upon the ability to see colors. His keen sense of smell compensates for his inability to see colors, and enables him to differentiate between things.

Extensive scientific testing on dogs supports the conclusion that they live in a colorless world. The testing done primarily focused on the dogs' responses to colors for food. Dogs could not tell the difference between one color, a signal for food, and other colors, that were not for food. Similar tests conducted on cats produced similar results, which led scientists to conclude that they, too, are colorblind and live in a gray world.

The inability of most animals to see colors, from an evolutionary standpoint, is quite simple to understand. Many colorblind animals have dull-colored coats, hunt for food in the dark of night, or graze in the dim twilight hours. Their other senses have developed to the point where the lack of color vision in no way impairs them. For them, life in a colorless world is neither a handicap, nor a threat to their survival.

The only animals, other than man, scientists can conclusively say have color vision are monkeys and apes. Both can be trained to open a colored door, behind which is food, and man can be trained to open a refrigerator door of any color!

  • "My well loved dog, Bella, was well taken care of with gentleness and excellent care. She is so much healthier after her dental treatment. I highly recommend Dr. Hall and his staff. They truly care and have exceptional communication regarding the recommended and provided care."
    Catherine
  • "Our little dog needed extractions. We found the Ocean Animal Clinic and Dr. Hall. They took fabulous care of him -- even including a nail clipping and ear check. Both the vet and the staff were open and transparent. The surgeon was top notch and the staff really cared about our dog and us. Our little guy bounced back quickly. All this for a lot less money than we feared as well. Highly recommended!"
    Terra
  • "Dr. Hall and the staff at Ocean Animal Clinic are truly unique. Most vets are compassionate but always peddling unnecessary expensive services and drugs. Dr. Hall is compassionate, direct and alternative. He really seems to be in tune with the animals.

    My baby, Harry, is ill and his prognosis is not what a mother wants to hear. But, Dr. Hall was so good with him and also our girl Roxy.

    Just a truly decent, loving Vet. Thank you."
    Jennifer
  • "The Ocean Animal Clinic staff have been caring for my adult turtles since 2011 and I cannot imagine trusting another veterinarian with their care. As a college student he was able to help me find ways to improve the care I provided my pets and his payment options (accepts CareCredit!) helped ensure that my pets received the medical attention they needed on time.

    I consider Ocean Animal Clinic a part of my family and would recommend their services to anyone without hesitation.

    Thank you, OAC!"
