Especially if you have a dog that's an escape artist.
We don't know ~how~ he got out, only that he did... and that he was smart enough to get home. It's just a shame he did it.
I didn't mean to imply that's what happened with this. You're correct that we don't know the circumstances of this story. I was just generalizing to the fact that so many "kind" kennels and vets refuse to use chokers when they could be the difference between life and roadkill. If it turned out the dog "slipped out" of some "kind" collar, that would just be 1 definite thing I'd put on a list of "suable" negligence. Along with just a few other things, like lousy kennel fencing, etc. But I'm still not a sue-happy person, so it'd have to seem egregious.
