Why do dogs eyes remain open after euthanasia?
The muscles around the eye that cause the eyelids to close require instruction from the brain to contract and close the eyelids. After a dog is euthanized, the brain no longer sends those instructions to the muscles so they no longer contract and the eyelids fall open. It is normal, and a lack of ability to blink when the eyelids are touched is one good indication that the dog is no longer capable of feeling anything.

Therefore, the number of times the nostrils open and close in one minute would typically be more frequent than the number of times the throat moves up and down in one minute.
