It's so disheartening to read this, especially when you went to such great lengths to keep Sitka safe the LAST time he was loose. I find it downright rude of his owners to make seemingly NO effort at all to keep their dog in AND get him a decent collar (which, by the way, didn't you give them one?! )

It's clear to everyone that you're trying to HELP Sitka, and the least his owners could do is show some respect and gratitude towards you by keeping their dog fenced.
