When I was in high school, this was an expression used when someone was going off to have sex with someone else.
"Hey girl, where are you going? I though we were hanging out?" And she says, "Oh, I need to go see a man about a dog." And then winks at you. Lol.

"To see a man about a dog" is the cunning inversion of "to see a woman about a pussy" (to have sex with a woman).
Friend 1: "I've got to see a man about a dog..."
Friend 2 : "ah, and a woman about a pussy"
Friend 1: "you know it!"
Friend 2 : "ah, and a woman about a pussy"
Friend 1: "you know it!"

An euphemism used to avoid telling of your true destination, often in reply to an awkward question. In Great Britain, it is commonly used as a euphemism for going to the toilet.
"Are you and your wife coming out tonight?" "Uhhhh, I'm going to see a man about a dog."
"How come you're leaving the table?" "I'm going to see a man about a dog."
"How come you're leaving the table?" "I'm going to see a man about a dog."
