Substitute, then hit Pokémon with move. Earthquake has good coverage thanks to STAB. Rock Slide hits Fliers and Sludge Bomb hits Grass-types and Heracross. Beat Up 2HKOs Blissey with a healthy team, assuming you have an average base Attack stat of a little over 80 (Dugtrio has 80 base Attack, for comparison), but Substitute can be used to ease up prediction when you come in on something like Raikou or Electabuzz Thunderbolt.
Other Options
Screech basically ups the power of its attacking moves and could maybe force something to switch in a UU battle. Hidden Power Flying can be used for Heracross and Hidden Power Bug gives extra coverage for Exeggutor. It also hits Celebi.
Opinion
Dugtrio is cool, but all it has is Speed—and Speed doesn't account for as much as it did in RBY. All of its other stats are lousy.
Counters
Suicune, Starmie, Slowbro are just some of the many Water-types that are not weak to Earthquake. Donphan can take anything Dugtrio tries to throw at it and just hit it back with a STAB Earthquake of its own. Forretress can set up Spikes and take little damage with its massive Defense. Skarmory is immune to two of Dugtrio's attacks, and isn't weak to the third. Gligar is in the same boat as Skarmory, except it 'only' resists Sludge Bomb.
