What is a good medicine for fleas, ticks, and worms?

I have a 14 month old chihuahua and we made sure that we got him to a vet when we first got him. The vet has a really quick treatment for fleas (they fall off within one hour) and the worms, and ticks, they give in topical medicine. Then he also got the injection for the distemper and parvo. Front-line is a good topical medication you can use on your dog. Oh!! and don't forget the heart worm pill. Interceptor is what I give my dog!!! Hope this helps!!!!
