Neighbor’s dog won’t stop barking and I don’t think anyone is home for hours?

My neighbor’s dog is a puppy so it’s not unusual to hear him bark spontaneously.

However, this has changed for the past 1-2 days. I’m having trouble with falling asleep due to the noise. The dog is barking persistently most of the day at the window and I can hear him cry too. 😭

Neighbor’s lights are on all day, so I tried knocking the door, but no one is answering. My building doesn’t have a responsive property manager either.

At this point, I’m more concerned about animal neglect or if something happened to the owner inside the unit. I thought about calling the police for wellness check, but was concerned that this is too dramatic. Thoughts?
