What medication is used for deworming in dogs?

It depends on the life stage that they're in. Maybe as a puppy, they'll get liquid formulations, like Panacur or Nemex. If they get older and they're not on prevention, unfortunately, we might do a one-time administration of something like Drontal.

The medication used depends on the type of worm. Sometimes we'll use Pyrantel, sometimes Fenbendazole, sometimes Proziquantel. Depending on if they're resistant, there might be some other medications we have to use.
