Question: To the best of your understanding, what is the Jewish perspective on the fate of an animal upon death? Are they considered to have a soul? Does a dog, who gave unconditional love and had been a loyal and brave companion, just disappear?
Answer: Animals are considered to have a nefesh, the lowest level of a soul. This is distinct from humans who have much more developed souls. Although animals can be loving, brave and loyal, we do not see them as having free will, but rather as acting instinctively. As such, they do not have the ability to earn merit and greater holiness for themselves as would a person who has the ability to use his or her free will in choosing right from wrong, good from evil.
