So to answer your question from the previous comment: you have to go to the abandoned hut in the forest at friday night. The event is happening over there, not in the shop in Bareshade.
The dog is still being improved. You should have a new icon in the reinforcement screen (The one where you upgrade buildings).
There's not much to do in this update if it comes to bandits. In 0.9 there will be a boss fight.
