PM me your email addy, I'll send it with a note to the dog owner and we'll let him weigh in.  If he doesn't reply, then I'd suggest changing things enough to be respectful.

Thank you paynesgrey that sounds like a good plan.
Okay, where do I get your PM?  I'm still new to this forum and don't know all the ins and outs.

Prophet224 - also good advice as the incident was very painful for the owner.

I have a short story idea that's been fermenting in my brain.  (It may never see the light of day, but it's been rumbling around up there for awhile.)  It's about pets and ghosts - more than that I'm not going to go into.
Anyway, had a hazy idea for the start and the finish.  The middle is where I usually bog down.
I was over on the pet thread when someone posted about their dog and something that had happened to her.
The incident and even the name of the dog would be perfect for my story.  It cleared a lot of the haze away.
I posted to the owner/poster to please get in touch with me.  But it looks like they've left the forum completely.
Ethics question.  Can I use this incident as is, or would I, should I change some things, or should I use it at all without having talked to the original poster and gotten permission??

As someone pointed out earlier if you don't sedate them they will go into shock and die fairly quickly.  So if keeping them alive is the game then sedatives are called for.  Besides, if the person knew that such damage had been done to them - the threat of the sedatives wearing off would be a really nasty form of torture.  (Brrrr, I just creeped myself out by thinking of that!  Gack!)

Along with heavy sedation, you could try lowering the person's body temp.  Slows the bleeding, slows the heart and tends to keep them sleepy and docile.
