Many writers have trouble selecting the right pronouns when they are writing about a specific group or individual members of that group.
You should always use singular pronouns for singular nouns. Really. A breed of dog is singular, as is a company. If you are writing about a pet monkey, the pet monkey can be referred to as "he" or "she" . . . or even "it". The monkey won't mind. But your editor (who may or may not be a monkey) will mind if you refer to the monkey as "they."

Another faux-pas in the writing world is using the pronoun "one," when you should be using "he" or "she." Using "one" is old fashioned and stuffy sounding, as in:
Use "he" or "she" "he/she" can be cumbersome; the reader will forgive you for choosing one or the other in order to sound up-to-date on writing trends. ("They" is becoming more accepted, but it still rankles to prescriptivists.) If you're addressing the audience, it's also perfectly acceptable to refer to your reader as "you." This sounds personable and makes your article accessible to the reader.
