Some types of dogs have a much sharper vision of man as man has a vision of 180 degrees and the dog has a vision that is bigger and which is somewhere around 270 degrees. Their vision however is not so important for them because the dogs are so good sense of smell to them, it is still a big advantage compared to their vision that is just so clean.
Their smell is more than 70 times stronger than the one we have and this is their great advantage that we use by certain types of dogs that are helping to find what we could find. The question, however, that all colors dog can see and recognize. Some say that the dog daltonist and does not recognize that color, but some of the last survey however shows that some types of dogs can still see some color and to recognize them. Maybe will still take time to discover this mystery, and until then we can do is wait for time to pass in order to learn more about our best friends of all the animals that exist today in the world.
