2. Dogs are naturally color blind
For some inexplicable reasons, it was once believed that dogs could only see in black and white. This belief was held as a fact for a very long time, and it is only due to the advances in scientific research that a different point of view has emerged.
Fact: Dogs do have color vision, but this greatly differs from the human understanding of perfect color vision. Due to the types of cones in a dog’s retina, a dog’s color vision leans more on the blue zone of the color spectrum.
