What Do You Call a Male Dog?
What Do You Call a Male Dog?
Last updated: July 2026. It sounds like it should have a one-word answer, and it does, but the full picture is more interesting than most people expect. So, what do you call a male dog? He is simply called a "dog", while the very same word doubles as the name for the whole species. Around that fact sits a small, precise vocabulary used by breeders, vets and kennel clubs. With 10.6 million pet dogs in the UK, plenty of us use the word daily without ever needing its narrower sense. Here is the full rundown of the terminology, where it comes from, and when each term is actually used.
What is a male dog called?
A male dog is called a dog. That is the correct, technical term. The American Kennel Club glossary defines "dog" as a "male dog or term used to refer generically to all dogs, male or female." In other words, the same three letters mean both "male canine" and "the species as a whole", and context tells you which is meant.
This double duty is why the question feels oddly slippery. When a breeder says "the litter had three dogs and two bitches", they mean three males and two females. In everyday speech, though, "dog" almost always refers to the animal in general, which is why most owners never need the narrower sense at all.
"Dog: a male dog, or a term used to refer generically to all dogs, male or female." — American Kennel Club glossary
What is a female dog called?
A female dog is called a bitch. Despite its use as an insult in general English, in the world of dogs it is simply the correct, neutral, technical term, the direct counterpart to the male "dog". The AKC glossary defines it plainly as "a female dog". Breeders, judges and veterinary professionals use it without a second thought, and it is the word you will see on pedigrees and in breed standards.
If you would rather avoid it in casual conversation, "female dog" is perfectly clear. But there is nothing improper about "bitch" in its proper context, and knowing it helps you read paperwork and understand your vet.
What are the breeding terms: sire, dam and stud?
Once dogs become parents, they earn new titles. The AKC glossary defines a sire as "the male parent" and a dam as "the female parent". So a puppy's father is its sire and its mother is its dam, terms shared with horses and other pedigree animals.
A stud, or stud dog, is a male kept for breeding; the AKC defines a stud dog as "a male dog used for breeding purposes". The distinction people often miss is this: a stud becomes a sire only once a mating actually produces a litter. So every sire has stood at stud, but a stud dog is not a sire until he has fathered puppies of his own.
What is a neutered or entire male dog called?
Two more words come up whenever health or breeding is discussed. A male dog that has not been neutered is described as entire, which the AKC glossary defines as "a dog whose reproductive system is complete". Its opposite is neutered; for a male the operation is castration, sometimes called "the snip", while the female equivalent is spaying.
You will occasionally hear an entire male called a "whole" dog in casual speech, but "entire" is the term on paperwork and in breed rings. None of these words is a judgement. Whether and when to neuter is a welfare and health decision best made with your vet, and the right answer varies with breed, size and circumstances. For terminology, the point is simply that "entire" and "neutered" describe status, not type.
Are there other words for a male dog?
Beyond the formal terms, a few everyday words describe a male dog by type rather than sex. A crossbreed or mongrel is a dog of mixed or unknown parentage, as opposed to a pedigree or purebred dog registered to a recognised breed; "mutt" is the affectionate, informal version of the same idea. You may also meet cur, an old and mildly disparaging word for a mongrel or an ill-tempered dog, now rare outside dialect and old books.
None of these is a synonym for the neutral, technical "dog". They tell you about a dog's breeding or temperament, not whether it is male. For a male specifically, "dog" remains the precise word, with "sire", "stud" and "entire" adding detail about parentage and breeding status.
What do you call a young or baby dog?
A young dog is a puppy. The AKC glossary draws the line by age, defining a puppy as "a dog under 12 months of age". After a dog's first birthday it is generally considered an adult, though physical and mental maturity varies a great deal by breed and size.
You may also meet the verb whelp, which means to give birth to puppies; a bitch in the act of giving birth is said to be whelping, and a very young puppy is sometimes called a whelp. A group of puppies born together is a litter. These are the words that turn up on breeding paperwork and in conversations with breeders and vets.
What is a group of dogs called?
A group of dogs is usually a pack, a word carried over from their wolf ancestry and still used for hounds worked together, as in a pack of foxhounds. A group of puppies born to one mother at one time is a litter, and the building or business where dogs are bred or boarded is a kennel, which is why breeders often trade under a registered "kennel name".
In everyday life you will rarely need "pack", but it surfaces in dog-training talk and in the names of working hunts, and it is the correct collective term when you do. Unlike the tidy dog-and-bitch pairing, these collective words are more about function than sex.
Do foxes and wolves use the same terms?
The dog vocabulary reaches beyond domestic dogs into their wild relatives. Foxes borrow it almost wholesale. According to Wikipedia, "male foxes are known as dogs, tods, or reynards; females as vixens; and young as cubs, pups, or kits." So a male fox really is a "dog fox", the exact counterpart to a "vixen".
The wider Canidae family, which includes wolves, coyotes and jackals as well as dogs and foxes, follows the same logic: males are often called dogs and females bitches, with the young called pups or cubs. It is a neat reminder that "dog" sits at the centre of a whole family of animals, not just the one asleep on your sofa.
Where do the words "dog" and "bitch" come from?
Their origins are genuinely mysterious. According to Wiktionary, "dog" comes from Middle English "dogge", from Old English "docga" (also written "dogga"), but where that Old English word itself came from is, in the words of etymologists, uncertain. It is one of the odder unsolved puzzles in English word history.
Stranger still, "dog" was not originally the main word for the animal. As Wikipedia records, the general Old English word was "hund", the ancestor of "hound", and "dog" referred only to a particular type. By around the sixteenth century the two had swapped roles: "dog" became the everyday word for the species, and "hound" narrowed to mean a dog used for hunting. That is why we still speak of a "foxhound" or "greyhound", but simply "a dog" for the family pet.
"Bitch" has a clearer pedigree. Wiktionary traces it to Middle English "bicche", from Old English "biċċe", a straightforward Germanic word that has always meant a female dog. Its use as an insult came much later; the original, and still technically correct, meaning is the one used in the show ring.
Quick reference: dog terminology at a glance
For a fast recap: a male is a dog, a female is a bitch, a father is a sire, a mother is a dam, a male kept for breeding is a stud, an un-neutered dog is entire, a youngster under a year is a puppy, a group born together is a litter, a group of adult dogs is a pack, and to give birth is to whelp. Keep those terms straight and you can read almost any pedigree or breeder's advert with confidence.
Does this terminology vary between countries?
The core terms are shared across the English-speaking world. So does the term for a male dog change on either side of the Atlantic? No, it is the same word: a dog. British and American kennel clubs alike use dog, bitch, sire, dam, stud, entire, puppy, whelp and litter in the same way, so a pedigree reads the same in Manchester or Missouri.
Everyday nicknames differ more; a British owner might say "lad" or "boy", an American "pup", but those are affectionate slang, not official terminology. When precision matters, on registration papers or at the vet, the formal vocabulary is reassuringly consistent.

FAQs
What is a male dog called in breeding terms? In breeding, a male dog is called a dog, and once he fathers a litter he is that litter's sire. A male kept specifically for breeding is a stud or stud dog. A male that has not been neutered is described as entire. These terms are standard on pedigrees and in veterinary use across UK and US kennel clubs.
Is bitch really the correct word for a female dog? Yes. In the context of dogs it is the correct, neutral, technical term for a female, defined by kennel clubs simply as a female dog. It is the direct counterpart of the male dog and is used routinely by breeders, judges and vets, whatever its use elsewhere in English. On pedigrees and breed standards, it is the standard word.
What's the difference between a sire and a stud? A stud is a male dog kept for breeding; a sire is specifically the male parent of a particular litter. A stud dog only becomes a sire once a mating results in puppies. So every sire has been used at stud, but a stud dog is not called a sire until he has actually fathered a litter of his own.
What is a baby dog called? A baby dog is a puppy, defined by the American Kennel Club as a dog under twelve months old. A group of puppies born together is a litter, and the act of giving birth to them is called whelping. After about a year a dog is usually regarded as an adult, though this varies with breed and size.
What do you call a male dog used for breeding? A stud, or stud dog, is the term for a male kept for breeding. He becomes a particular litter's sire only once a mating produces puppies, and if he has not been neutered he is also described as entire. So the same male can be a dog, a stud and, in time, a sire, depending on which fact you are stating.
What is a male fox called? A male fox is a dog fox, and also, more traditionally, a tod or a reynard, while a female fox is a vixen and the young are cubs, pups or kits. The dog-and-vixen pairing shows how the domestic-dog vocabulary was borrowed across the wider canine family.
