I don’t know about dogs, but since the prompt states “pets”, I will point out that cats may leave (or hide if they are not allowed out) to die alone if they sense it.
My oldest tried to leave, but he returned a week after we gave up the hunt and was diagnosed with an aggressive tumor when we had him checked out. Inoperable. Put him down after it broke through the skin and literally started rotting. Only one who tried to leave. Second had a brain tumor, would not have been able to find his way out. Third had jaw cancer, put him down to avoid removing half his face. Fourth died of natural causes: a horrifying seizure. I would not recommend waiting for natural causes.
