"It's on owners to do their best to prevent police from interacting with their unrestrained dogs."

This there is the problem. Why should the general public be afraid of police when on a daily basis their dogs do interact with other professionals and workers?. This is because of fear inculcated by their behavior and there is no recourse later.

Police are doing a very different job than any other service worker likely to interact with a dog (as I explained in the other comment).

The general public has very little interaction with police officers at all. A random member of the general public should have approximately zero fear of their dog being shot.

The people having their dogs shot are usually doing something to attract the attention of police and/or not being responsible with the care of their dogs.

In other cases police officers are wrongfully shooting dogs. These are almost certainly the minority of cases but clearly this number should be as close to zero as possible. Police officers should be fired and sued in cases of negligence.
