I'm writing an example of constructing logic, and I need to differentiate between an adult female dog, an adult male dog and a puppy and am searching for polite terms.
Unfortunately, the word "bitch" has impolite connotations, so I'd rather not use it, but I'm not sure of any other terms for a female dog. Likewise, I don't know of a gendered term for a a male dog, apart from 'dog'.
Given the linguistic baggage that the term 'bitch' has in non-specialist areas, is there an alternative, polite term for an female doga 'female dog'?
For context: in the logic I'm describing, if the dog is young it is a puppy'puppy', otherwise if it's female it's a term X'term X', or if it's male it is a term Y'term Y'.
