What is a male dog called? And a female, and the rest of the vocabulary
A male dog is simply called a dog. The word doubles as the name of the species and the name of the male, which is why the question is asked so often.

The short answer: an adult male dog is called a dog. An adult female is called a bitch. That is the whole of it, and the reason the question comes up at all is the collision — English uses the same word, dog, for the species and for the male of the species, so there is no obvious counterpart to bitch in the way that cow pairs with bull.
The terms that only apply in breeding contexts
- Sire — a male dog considered as the father of a particular litter. He is a sire in relation to those puppies, not by nature.
- Dam — the mother of a particular litter, used the same relational way.
- Stud — a male kept for breeding. Unlike sire, this describes a role he holds rather than a relationship to specific puppies.
- Whelp — a newborn or very young puppy. As a verb, to whelp is to give birth.
- Litter — the puppies born together from one pregnancy.
Two of those are frequently misused in casual conversation. Sire and dam are relational: a dog is the sire of a litter, in the same way a person is the father of specific children rather than a father in the abstract. And a male dog who has never been bred from is not a stud; he is a dog.
Why bitch is the correct word, awkward as it is
The word carries obvious weight as an insult, which makes many owners avoid it entirely and say girl dog or female. In veterinary practice, in kennel-club paperwork and in any breeding record, bitch is the standard technical term and is used without embarrassment. Its use as an insult is a much later development than its use as a description; the animal sense goes back to Old English bicce. Vets are not being coarse when they use it, and there is no more correct alternative.
Terms for age, and the ones for groups
A puppy is generally a dog under a year old, though the practical line varies by breed — a small breed is physically mature well before a large one, and a Great Dane is still filling out at eighteen months. There is no widely used specific word for an adolescent dog, which is a gap in the vocabulary that anyone who has lived with a nine-month-old dog will feel keenly.
A group of dogs is a pack, though the term properly describes hunting hounds working together rather than any collection of dogs in a park. A pair of hounds worked together is a couple, and hunting kennels traditionally count in couples — a detail that survives in old records where a pack is listed as, say, twenty-two and a half couple.
The word that causes the most confusion: mongrel
Mongrel, mutt and crossbreed are not interchangeable. A crossbreed has two known pedigree parents of different breeds, and increasingly has a portmanteau name attached to it. A mongrel has mixed and unknown ancestry. Mutt is informal and used for both, affectionately in most contexts. Kennel clubs use crossbreed for the first and mongrel for the second, and the distinction matters if you are filling in a form rather than describing a friend.
