Safeguard works on all worms, including tapes. It's available at many pet stores now in a dog dosage.
ETA: You might want to go ahead and get your own dog a packet since none of the monthly treatments treat tapes. You may not be seeing tapes but if the stray has been hunting rodents to survive, he's more than likely carrying them, too.
