Simple, unlock the attack dog by redeeming your xp you from the events. Earn xp by completing waves or destroying rouge bases. You need to save 2,250 (I'm pretty sure thats the amount). The last event (operation warlord) gave you 600xp per defense wave and 800 per attacking wave. So do the math.

The events took place once a month, but because of operation warlord, it could be once every half a month.
