I have Charlie on Advantage Multi, which is once-a-month topical. It kills fleas, heartworms and intestinal worms. My last dog was on the once-a-month oral Sentinel which is also a wormer in addition to flea control/heartworm.

You're monthly flea control and/or heartworm medication may also be an intestinal wormer. The vet may or may not have considered that if you were asking her specifically about worming.
