lawn and the barking dog.

You might consider calling your town/city code enforcement office. If code enforcement can see how bad the backyard looks the city/town might be able to cite the homeowner for the debris. I can tell you that where I live, a yard full of debris would probably get written up and the homeowner given a time period to clean up the yard or the fines would start. Here you can even go on line and file your complaint and request an update on the outcome. Debris all over the lawn represent a hazard plus that in and of itself can negatively impact home values. I would be really concerned about the danger the debris poses to the dog.

Does your neighbor provide some type of doghouse outside for the dog? Adequate food and water? Where I live, you are required to provide adequate shelter for an animal kept outside. If the dog does not have adequate shelter that, combined with the debris and endless barking would be grounds to file a complaint with Animal Control. If the family is not properly taking care of this dog, you are not doing that dog any favor if you don't speak up for it to Animal Control.
