In some cultures, the puppy is also used as a food source. The total number of puppys, which also includes puppies, in the whole world is estimated to be around four hundred million.

With the passage of time the puppy has developed in a number of different breeds which go range into the hundreds. Each breed has its own different features, and the height can go from a few feet in the case of the Chihuahua, to around a few feet in the case of the Irish wolfhound. There are also differences in the color, which ranges from light tan to brown and to dark chocolate or red, and from white to gray and to black. The patterns are of a wide variety as well.

According to the DNA evidence, it was around fifteen thousand years ago that puppys began to be domesticated from the wolves, who themselves were descendants of other wolves. Puppys then gave birth to puppies, which were also domesticated by the humans. According to these dates, the puppys and the puppies they give birth to also have the status of being the first animals that began to get tamed by humans.
