My wife and I have a young Belgian Malinois, and at about a year and a half of age she started flopping down onto the floor in a very loud and obnoxious manner whenever she was frustrated or in a fit of pique. Being very bony, she makes a loud thump.
It wasn’t long after she started this that my wife remarked,
“It sounds like a body hitting the trunk of a car.”
It was all I could do to turn to her and query just how many dead bodies she had to have transported in her car’s trunk to get that intimately familiar with the sound.
