I really, really despise the Ayatollahs of Iran.

3. I'm going to push back on that a bit. For a dog's presence to be "unhealthy" requires

poor housekeeping by any reasonable measure.

And, dogs to not defecate "anywhere" unless sick, extremely stressed, or very young puppies.
They have a desire to keep their home (den) clean of such refuse.

Also, dogs to not steal food when they feel like it, unless they have never been trained not to do so.
If dogs stole whenever they felt like it, there would be no such thing as hunting dogs.

Just because some cultures consider dogs unclean does not make it true.

Just like some cultures consider menstruating women unclean doesn't make it true.

Not all cultural beliefs are sacred or should be considered so.
