Question:
I was told that dogs see everything only in black and white. I was very sad to hear that, considering all the beautiful colors that God has created. Could you please comment on whether dogs see in color or black and white? I'm sure others will like to know.

Answer:
To put your mind at rest: Dogs do not see monochromatically, i.e., in black and white. They can see two primary colors: blue-violet and yellowish-green. But they cannot distinguish red from orange or orange from yellow.
Their night vision is far superior to ours, as is their sense of hearing. But it is their sense of smell that sets them far apart from us, their natural endowment being demonstrated in their ability to track scent trails often several days old. Their sense of smell may also help them detect hormonal and emotional changes in humans that affect our pheromones and body chemistry. So although they might not have the same visual experience as humans, dogs certainly outmatch us in other realms of the senses. It is also evident from the time they take to sniff various spots and from their apparent olfactory rapture during a walk that they are deriving considerable pleasure just like us, enjoying spring blossoms and autumn leaves.
