When I had Bella pts due to a FLV related chest tumour, she lay on my sofa for a few hours while my boyfriend of that time was digging her grave. I was sure she was still alive. I didn't see any signs of breathing, it was just a feeling. That night, after she'd been buried, I felt the urge to get her in out of the bad weather, almost as though she were still alive. This haunted me somewhat.
For this reason, and for the reasons given by others here, if I ever need to have another pts, I will wait at least 24hrs before burying them, to allow time for any incomplete euthanasia to wear off. But I hope that my oldies go gently while sleeping.
These stories are really horrid, bringing up all sorts of fears of being buried alive.
I always thought that the overdose of barbiturate, or whatever, was so massive as to make death inevitable. Amazing what some people will do to save money on what must be fairly cheap medication.
