Did the owner of the dog that was shot get a fine or jail time for trespassing or his dog being off a leash or any of many laws that are usually broken by dog runners? Your story sounds like a pet running after deer on a neighbors land, not a pack of deer hounds with telemetry collars chasing deer so a hunter can shoot them. The fact is that nothing ever happens to the guys who knowing let their dogs run across property lines without permission.
At times they do! But, I leave it up to the officers and the courts to handle that one. As most here think that loosing the dog/dogs is enough. But one such case 2 dogs were returned to the owners and the owners were charged. The owners had to get both dogs put to sleep and now waiting on the size of fine as well as how much damage they have to pay back. So here the laws work for the people and not the people trying to take matters in their own hands. So I guess that maybe your problems down there. We have a habit of dealing with things. A responsible dog owner has to be accounted for as well. It's not a case of someone complaining because folks hunt different so we do not have nearly as much whining going on up here.
