You need to purchase your pack based on your Rottie's weight; so I can't tell you if a two-pack will be sufficient. Vets recommend treating 3 times; a week apart, just to make sure that all newly-hatched eggs have been taken care of, but I've found it seems a bit of overkill, and can result in sick dogs and/or their becoming resistant to the treatment.
I buy the twelve-pack, because it's the cheapest per tab; and then treat as needed. Generally one treatment is all that is needed. However, if you have your Rottie outside regularly, and they get fleas, the fleas will re-introduce the worm eggs, so re-treatment approximately every 2-3 months, or when you see symptoms (eggs in stool; rubbing of back-end, etc.) will be needed
