Dog Hearing and Sense of Smell The tests would indicate that our k9 pets don't put as much value on colors as humans do. A perfect example of this would be a dog who is allowed to lay on a tattered old couch in a spare room. He has curled up on this comfortable piece of furniture with no concern from his humans for many years. Suddenly, he is exiled from hopping up and resting his shaggy body on our newly reupholstered (in a fine, delicate tasteful green colored material) sofa. Our dog is very confused by this sudden change wondering, "Is a tasteful color of green dangerous or unhealthy for dogs?" The experiment the scientist's conducted with lights brings to mind a story I read about some time ago. The story is about a blind man named Bill Bowen and his seeing eye dog, Bud. Bowen was diagnosed as being legally blind, he only had a fine reminder of vision remaining at the peripherals Hearing Aid Pretoria of his eyes. This is why he required Bud to guide him through his travels each day.
In 1984, Bowen got arrested for drunk driving; as he was in the front seat of a car that had recently been seen weaving and erratically changing lanes down the road. When he was in court for this crime, he stated he was only a passenger in the car--Bud was actually the driver. The judge had some idea of the theory that dogs were color blind, "Witnesses say that the car did stop at the red lights and resume when the lights turned green. How could Bud do this since it is well known that dogs are in fact color blind?" Bowen, who was unaffected by the question said, "Bud has learned to determine that when the light at the top is lit, he needs to stop. And when the light at the bottom is lit, he can go." Just before the case was about to move on to the next stage, Bowen broke down confessing that he indeed was the driver of the dangerous car, and that he had lied about it. He admitted that he had indeed been drinking and driving the vehicle, and suddenly felt ashamed for trying to frame his loyal sight dog Bud. "Okay. But I still don't understand." stated the judge. "If you are blind, how did you
read the stop lights?" "Well," Brown spoke, "You see that really was Bud. He was in the passenger seat, and he would bark once to tell me if the light was red and twice if the light was green." http://hubpages.com/animals/DOGS-Do-They-Have-Good-Scents
