I noticed you mentioned the danger of the road to them last time.
That is a genuine danger to the dog, but not one that would be your fault. So warning them about it makes you look like a good person instead of a bad person, while still pointing out that the dog itself is in danger.
The one thing a pet has that a predator does not: an owner who might be trainable! (As in, you might be able to train an owner to keep a pet dog contained.)
No, I don't think you are getting "too soft." You are just dealing with the situation in a different way.
