First off acreage limits are NOT the answer.
2nd from few responses in this thread some of you have never took the time to visit or hunt with a dog man that cares where his dogs are and is willing to do what it takes to get dog/dogs where they need to be.

I would be glad for anyone on here to come hunt with me on a small acreage tract (30 acres- 500).

I am adamant that my dogs don't get out of drive and if they do I will have them back in drive before they gain 30 yards.
I run beagles ( not because they are easier to control but just cause I am a beagle guy). Big dogs can be controlled just as easy. It takes just a lil bit of time to work with them.

The response about people hunting small blocks of land and not cutting it off. This goes back to the dog man not spending time to collar break the dogs.

The alpha isn't fail proof but it is dang close. More and more dog clubs are going to the alpha and it is only going to get better for neighbouring properties.
