There are a wide variety of dog breeds with different colors, sizes, shapes, fur, and physical characteristics. The sheer number of dog breeds is more massive than with any other mammal, domestic or wild.
Can you believe that there are almost 400 dog breeds in the world, and this is just the best guesstimate since it’s continuously growing due to artificial selection? But, there is one limit to this variety, which is the physiology of a Chihuahua to Great Dane, cause they are descendants of ancient wolfs.
