You NEVER KNOW what may be happening at any given time. Hole blown through the house, have to leave. Can’t get back in the house. 9/11. Other crises more important than the dog right now.
Judgement of people is needed on a case-by-case basis. Generally yes you wouldn’t do that, but sometimes things happen.
Like I said, I have to go through a lot of surreal mental contortions to come up with an example. Perhaps if aliens hovered their mother ship above my town and threatened to use their death ray on every person who didn't leave their dog tied up unattended, then yeah, I might possibly consider it my best option. That is a real possibility.
