If you dodge everything, it shouldn't be a problem. You don't have to be greedy with an extra quick move, either. Is it really worth another 5-10 damage if you eat a Stone Edge or Hydro Pump? I think not.
Just swipe every time there is a yellow flash. Not sure what else to say about it unless you are having trouble dodging specific moves. If that's the case, just look up the move page on this here website, and it shows you when the flash animation occurs, damage window, cooldown, etc.
Everything you need to know about any specific charge move is there for the reading.
