A rescue dog — unless maybe really, really old — needs to be challenged constantly. And by challenged, I mean — these dogs are/were rescue dogs for a reason. :)

Challenges include games and tasks, and all that. These dogs need "work" to feel alive.

Your talking about police/fire/ems dogs, but they are talking about saved dogs from bad situations.

My bad. Language barrier! :)

I believe you're talking about "search and rescue" dogs. The others were talking about dogs that had been rescued from abusive or neglectful owners.

In any case, you are correct :)
