This isn't about legal dog-hunting. It's about illegal dog-hunting.
Exactly. It seems we have deviated from the OP, which in my understanding was the illegal use of dogs to drive deer to another property, to the ethics of using dogs where legal.
IMO , it borders on the line of unethical hunting , but it is perfectly legal in my county , so who am I to say .
Same can be said about many forms of using dogs for hunting. Running bears, running cats, running 'yotes. Yet most think that running rabbits and pointing upland game is much more "ethical"....almost "gentlemanly". What most folks don't realize is, that many times, without the use of dogs, because of terrain, amount of area and high populations, that the use of dogs is the only effective way to control those populations. While there is still a need for some ethics involved, the legality of it, makes it "appropriate". Similar to trapping. One only has to look at raccoon and other ground nest predator populations, that at one time were heavily controlled by trapping and the use of dogs. Nowadays, no one traps and very few folks around here have "coon dogs". The ground nesters like wild turkeys, grouse, quail and pheasants have been heavily impacted.
IMO , it should be against the law for anyone to come on your property if it is posted .
This comes down to how your state looks at the rights of property owners. Here in Wisconsin, growing up and hunting in the 60s, I could hunt any property that did not have a signed no trespassing sign every 40 yards around the perimeter. At the same time, most folks would let you hunt if you asked. Since then the rules have changed several times as sentiment about property ownership has changed. Now, no posting at all is needed unless you border public land. Even then, you are responsible to know who owns the property you are on and need to have written or oral permission. If your dog is on a property without permission, you can be charged/fined with trespassing. If there is proof an arrow or a bullet from your gun lands on the neighbor's property, you can be, in extreme cases, be charged/fined for trespassing. Anytime a dog is allowed loose, is off the owners property/property it does not have permission to be on, and not under the direct control of it's owner, it is considered "running at large". All of this had come about because of the many things mentioned here and the state's stance on property owner's rights.
A friend had a problem with a neighbors dog. He loaded it up and drove it close to fifty miles away and had a friend take it to his local dog pound as a found lost dog.
There are ways to end the problem.
In my case, there's no need to haul the dog 50 miles. I just call the local humane society and a local LEO comes and picks up the dog and takes it to the local pound. Last time I was asked why I just didn't call the number on the collar. My response was, I don't need some irresponsible dirtball coming to my house to pick up a dog, he doesn't control. He agreed.
