Assuming you mean "teenage" in a figurative sense... An immature pig is generally called a shoat or piglet. An unbred female pig is called a gilt. (There's not a corresponding term for an unbred male pig, though a male pig castrated before puberty is called a barrow and one castrated after puberty is a stag.) If you meant it literally, then a pig of 13-19 years of age would be called a boar or hog if male, or a sow if female.
