What is the difference between a breed and species in dog?

A breed is a group or subspecies of dogs that have been selectively bred to have certain physical characteristics, temperaments, and abilities. Each breed has its own distinct characteristics, such as size, coat type, colour, and personality traits.

A species, on the other hand, is a taxonomic classification that refers to a group of organisms that are capable of interbreeding and producing fertile offspring. In the case of dogs, the species is Canis lupus familiaris. This species includes all domesticated dogs, as well as wolves, coyotes, and jackals.

In other words, a breed is a subspecies of a species. All dogs are part of the species Canis lupus familiaris, but there are many different breeds of dogs, each with its own unique traits.
