Disc Color Choice for Canine Disc Play

An excerpt from Disc Dogs! The Complete Guide by Peter Bloeme and Jeff Perry, Co-founders of Hyperflite, Inc.

Canines were once thought to be color blind, that is, that they could see only black and white and shades of gray. Canine eyes, like human eyes, contain within their retinas, certain light sensitive cells called cones and rods. Cones allow us to see small details as well as colors while rods allow us to detect motion and to see well in low-light conditions. Dogs eyes have rod-dominated retinas and possess only about ten percent of the cones that human eyes have. In other words, dogs see great in low-light situations but canít see colors as well as humans can.

Modern studies on canine eyesight generally agree that dogs:

Have eyes that allow for the optimal tracking of objects in motion
Have excellent night or low-light vision
Have limited or less-developed color vision
Have less developed close-up vision

The colors that canines are believed to see well include: Purple, Blue, Yellow, and Red. However, canine vision depends upon so many variables, including ambient light, background, motion and even the shade of a particular color, that the proper disc to use in a given situation should best be determined after careful consideration of all of these factors and perhaps a few test throws to your canine.

Generally speaking, if you wish to maximize the visibility of a disc to your canine then you must seek a disc that is clearly distinguishable from background clutter by virtue of the contrast that it presents against the background in question. In making your disc selection, beware of the amphitheatre effect which can occur when opposite ends of a playing field have very different backgrounds. For instance, a throw in one direction might be against a milky-white overcast while a throw in the opposite direction might yield a background of green trees or brown mountains. Polar opposite backgrounds that occur at the same competition venue should cause you to select a compromise disc color that will be viewable by your canine against both backgrounds. And just to make things a little more complicated for you, research has also shown that the color green appears to canines to be yellow. So, even though dogs see yellow as yellow, and see the color yellow well, they also see green as yellow. A yellow disc against a background of green trees in certain light conditions might be difficult for your canine to track. The only way to be sure that your canine can see a particular disc well would be to make a few practice throws to your canine and make sure that the disc can be easily seen by your canine under the conditions present.

Also, since conditions change during the course of a day, the disc you choose in the morning, may not be the same disc that you should use in the afternoon.

Interestingly, the results from one of the key studies done on the interpretation of color by canines donít always correlate with the experiences of many disc doggers who swear by one disc color or another. These disparities suggest that between and among breeds, and even from canine-to-canine, dogs may not see eye-to-eye.

About the Authors

Peter Bloeme

Hyperflite co-founder, Peter Bloeme is currently director of the Skyhoundz Championships. In this role, he manages more than 100 Local Championships, 10 World Championship Qualifers, and the World Championship — reaching millions of consumers with messages of canine health and fitness.

Bloeme’s career of tossing, skipping, bouncing, spinning and twirling a plastic disc into the air began in 1974 when he won the Junior National Frisbee Championships at the age of 15. In 1976, at the age of 19, he won the World (human) Frisbee Championships at the Rose Bowl in California before 40,000 disc fans.

In 1983, Bloeme added a new element to his sport – a black and white Border Collie named Whirlin’ Wizard. The two went on to win the 1984 World Canine Frisbee Championships making Wizard, at less than 2 years old, the youngest dog to ever win the title. At the same time, Bloeme became the only person to win a world title both by himself and with his dog.

In 1990, Bloeme added a little magic to his routine – literally – with the addition of Magic, a black and white Australian Shepherd. Over the years, Bloeme, Wizard and Magic performed hundreds of disc dog demonstrations at sporting events including Major League Baseball, National Football League, World League football and National Basketball Association games.

Bloeme and his canine companions have also performed numerous times before sold-out stadium crowds all around the world. They have performed half-time shows at sporting events and have made public appearances in countries including Canada, China, England, France, Germany, Italy, Japan, Spain, and Sweden. Perhaps his most notable appearance was at the 1995 Japanese Baseball All-Star Game in Hiroshima, Japan where, after the seventh inning, the game was stopped for a ten minute exhibition by Bloeme and four Japanese dogs. Bloeme’s performance was viewed live by a sold-out crowd of 40,000 fans plus an estimated 26 million people on television through the Tokyo Broadcasting System.

During the 1970’s, Bloeme served as technical advisor to CBS Sports for a half-hour television special on Frisbee and toured Europe as a representative of the International Frisbee Association.

Bloeme and his dogs have appeared on television in the U.S. hundreds of times, including featured appearances on shows such as “Good Morning America,” “Late Night with David Letterman,” and on CNN and ESPN. You may remember seeing Wizard opening the Disney movie, “Flight of the Navigator.” In a Miller Lite television ad, Bloeme was responsible for the on-camera Frisbee action. Wizard even had a walk-on role in the spot. Bloeme has also served twice as the color commentator for Animal Planet in their one-hour show on the World Championships.

In 2001, Bloeme, Jeff Perry (1989 World Champion & Hall of Famer) and Greg Perry founded Hyperflite, Inc., a company dedicated to developing advanced disc technology. Their first disc, the K-10 for dogs was introduced in July of 2001.

Bloeme is author of the book, Frisbee Dogs: How to Raise, Train and Compete, a 192-page paperback, illustrated with over 300 photographs and the book, Skyhoundz Images, an 80-page hardcover photo book on the sport with captions in English, Japanese and Spanish ($19.95 U.S.).

Bloeme also co-produced, along with Jeff Perry, the internationally-acclaimed Disc Dog Training DVD, the top-selling disc dog training DVD of all time and Disc Dogs! The Complete Guide. At 360 pages, and featuring more than 600 color photos, Disc Dogs! is the most thorough and authoritative canine disc publication in existence.

Jeff Perry

Hyperflite co-founder Jeff Perry and his mixed-breed, animal shelter adoptee, Gilbert won the 1989 Canine Disc World Championship in Dallas, Texas. Prior to taking the World title, Perry and Gilbert won the Southeast Regional Championship for three consecutive years. Gilbert and Perry went on to be featured on NBC’s top-rated “Today Show,” along with numerous appearances on CNN and ESPN and other national and international media over the years. As a member of the ALPO Canine Disc Celebrity Touring Team, Perry was a media spokesperson for the 10-year period in which ALPO sponsored the Canine disc Championships.

Throughout the years, in countless interviews and public appearances Perry has extolled the virtues of adopting shelter animals. According to Perry, shelter mutts make wonderful companions and great disc dogs.

Perry and his canines have performed hundreds of times before sold-out stadium crowds at professional football and baseball games all over the world. Internationally, Perry has performed before huge crowds at Olympic Stadiums in Berlin and Barcelona and has made public appearances in Canada, China, Spain Germany, Italy, Japan, Mexico, and Puerto Rico. Gilbert and Perry were featured entertainers at the prestigious “Colare de Oro,” the Italian equivalent of the Westminster dog show.

While performing in Japan, Perry met the Crown Prince and Princess of Japan (the future emperor and empress of Japan) after one of more than 200 shows that he performed in Japan over a five-month period at the Animal Kingdom in Nasu. While in Japan, Perry and his dog Cosmic K.D. also entertained thousands of spectators in the Tokyo dome.

From 1990 to 2005, Perry served as the Chief Judge of the World Canine Disc Championships.

Perry, along with Peter Bloeme and Greg Perry, co-founded Hyperflite in 2000 and, shortly thereafter, designed and patented the revolutionary K-10 disc, the first canine disc designed exclusively for canine competition.

Perry, along with Peter Bloeme, co-produced the internationally-acclaimed Disc Dog Training DVD, the top-selling disc dog training DVD of all time. In addition, Perry co-wrote Disc Dogs! The Complete Guide, the most authoritative book ever written on canine disc sports.

In his spare time, Perry also serves as a Contributing Editor for Flying Disc Magazine.

A strong proponent of the health and fitness benefits of canine disc play for dogs and owners, Perry founded one of the first canine disc clubs in the country. Over the years, Perry has taught countless canine-disc aficionados to throw flying discs and helped even elite-level competitors improve their throwing abilities.

In addition to his canine disc activities, Perry still finds time to engage in some of his other favorite pursuits, climbing, backpacking and flying. Perry, a skilled pilot, has flown powered aircraft and hang gliders for more than 25 years and has logged more than 2000 hours in many types of aircraft. In fact, his aeronautical experience and understanding of aeronautical principles were instrumental in the design of the Hyperflite K-10 disc.

Perry received a Bachelor of Science degree (B.S.) in Journalism from the University of Maryland, a Juris Doctor degree (J.D.) from Mercer University and a Master of Laws in International Law (LL.M.) from the University of Miami.
