Today I was exposed to the fact that the female form of dog is bitch (just like bull (m) and cow (f)).
But I have never heard someone who called his female dog a bitch. So I suspect that in fact it is not in use, Isn't it?

In the UK, you can still use the term bitch without embarrassment, providing that the context is clear:
However, you might want to think twice before referring to someone else's dog as a "bitch".
I have the feeling that the term is falling out of use, partly because most dogs are given names and so it can easily be avoided. You can still hear the term on British television, mostly on nature and countryside programmes.
Thinking about it, a lot of gender-specific names for animals are used infrequently. You rarely hear male ducks called drakes, male geese called ganders, or female cats called queens. However, male cattle are still called bulls, and male sheep are still called rams, but then these are farm animals and that may be why the usage has persisted.
