How do you get the "4" achivement?

I'm stuck in the second scene of the game in the mobile home. After stepping out of the shower, a dog is heard barking and then nothing else happens. I've walked all around the home, tried interacting with things with the space bar, and even tried restarting from the beginning in case of a glitch, but I cannot seem to progress. Is this a bug, or am I missing something?...

Is there a specific order to Lu's games that I should play in? Eye to Me is my first game and I feel like I'm missing lore (not to mention I'm stuck). Any insight will be appreciated.

Just curious
