It's un GSD related, but have you ever heard from older people that if someone is sick or laying on a sick bed and a hound howls, that person or someone nearby is going to "leave this world"?
Ohhh! Thanks for the explanation. I have heard of that before, for some reason I was thinking rattling like an earthquake.A death rattle is a gurgling or rattle-like noise produced shortly before death by the accumulation of excessive respiratory secretions in the throat. Those who are dying may lose their ability to swallow, resulting in such an accumulation.
My research said that the death rattles are a strong indication that someone is dying and some other stuff that I failed to copy. At any rate, when my father was in hospice care and started making that sound, I looked at my nurse cousin and our expressions were identical. We had both heard that sound before. Hear it once, and you just know.
There is also agonal breathing, "an abnormal pattern of breathing characterized by shallow, slow (3-4 per minute), irregular inspirations followed by irregular pauses. It may also be characterized by gasping, labored breathing, accompanied by strange vocalizations".
