A dog, usually small and yappy, that is unwillingly acquired when a sexual partner moves into ones residence.
"Dude!! My girlfriend gave me a STD!"
"What, like herpes or something?"
"Nah man, a sexually transmitted dog. A white, fluffy, irritating Maltese Terrier named Paris that yaps all night and poops on my lawn. I so would not have slept with her if I knew that she was a carrier."
