I'm having trouble understanding the plot of the movie regarding the dogs' behavior. The film did not adequately explain why the dogs were becoming violent and how the objects falling from the sky were related to their behavior. The rocks began making strange high-pitched noises, which caused them to become aggressive. At the end of the movie, the family was surrounded by even more dogs while trying to escape to another town. I wonder if they could have used dog whistles to deter the dogs and if there were any survivors. It seems as though the movie may have been rushed due to budget constraints.
