The source account
VCA explains that cones help distinguish colors and that dogs have two types compared with three in typical human vision. AKC likewise describes dogs as dichromatic rather than restricted to shades of gray. This is a general anatomical account, not a way to count cone cells from a photograph or diagnose an individual animal. Our diagram uses words and ordinary colors, not a claim of direct visual reproduction.

A human comparison has limits
The articles compare canine color perception with aspects of human red-green color-vision differences. The comparison can help explain a concept, but it does not mean human and canine vision are identical in every respect. VCA discusses other differences in detail and light sensitivity. This site therefore avoids treating a human color filter as a complete dog-eye view.

Keep the subject of the sentence
A claim about cone types is not automatically a claim about object recognition, preference, health or safety. Those are separate questions. We do not turn two cone types into a ranking of intelligence, enthusiasm or training ability. A person can understand the broad color distinction without asking a dog to select between objects or repeat a task.
