Q: We have a dog that is very old and experiences much pain in walking and moving about. My father suggests having the dog put down by a vet. This would entail an intravenous injection. Described as “…a very high dose of pentobarbital or sodium thiopental. Unconsciousness, respiratory then cardiac arrest follow rapidly, usually within 30 seconds.” Is it permissible to put a dog down in this manner via lethal injection?
And Allah Ta’ala (الله تعالى) knows best.
