You are a superhost @Nongrat0 so I am suprised you have not being more proactive in managing this situation.
Why did you accept a booking for four people and a dog when the booking was for two adults and a child.
Why are you letting your guests leave the dog alone for most of the time disturbing you and your neighbours.
You need to take control. Tell them they are not allowed to leave the dog alone at the listing as it barks constantly and is disturbing the local community. Tell them they need to pay for the extra guest. If they are not happy with this tell Airbnb to cancel the booking.
I can't believe you still haven't updating your listing to say no pets.
