What term describes a male dog?

The term "dog" specifically refers to a domesticated male member of the species Canis lupus familiaris. In general, "dog" is commonly used to identify adult canines, regardless of their sex, but it is often particularly associated with male dogs. This term is well understood in everyday language and is widely recognized in both casual and formal contexts when referring to male members of the species in comparison to females, which are known as "bitches."

The other terms mentioned do not exclusively indicate male dogs. "Canine" is a more general term that encompasses all members of the family Canidae, including wolves, foxes, and domestic dogs, thus it lacks specificity regarding sex. "Pup," on the other hand, refers to a young dog of either sex and does not indicate gender. Lastly, "wolf" refers to a wild member of the same family, but is a different species altogether and does not pertain specifically to domestic dogs.
