All you have to do is breed a male Pokemon that's in the same Egg group as Lotad - and knows the move Giga Drain - with a female Lotad. Then, you'll get a Lotad with Giga drain.. If you go here you'll see what Pokemon you need to breed with Lotad.. There are a lot of Pokemon that can give Lotad Giga Drain...
Ps. If you're breeding for a Pokemon with perfect IVs make sure to check the Day-Care because they might delete the move to replace it with a new one... When I need to breed perfect IVs with Egg moves I keep deleting every move from the Pokemon and I only leave the Egg move. Hope I helped!
