It is so hard to justify the pimping of pets that can be the only ones in a household. Are these households on desert islands? Any pet has to be able to function in society or it should not be allowed in society. Shit happens as they say. The gardener leaves the gate open, an earthquake takes down walls and opens doors, the pet runs out the door. Then what happens when this animal aggressive (and there is a thin line between animal aggression and people aggression) pet does get out? They will kill someone's pet, maybe attack a child since children are seen differently from adults by canines.
This is immoral and irresponsible. Then again, we are talking about Best Fiends, aren't we.
