Part of what gives a hunting dog its drive is penned up aggresion, meaning when he is penned up all week when you turn him loose on Sat. he should knock the back of the woods out looking for something to get into.
Based on my personal experience, I question that logic.
What would your dog do if you hunted him several times a week, without the penned up agression? Would he stop hunting? Does he hunt harder if he is on a chain 6 days vs 3 days?
During the week, if not hunting, I let my dogs out to run around and cut loose, they get cut loose in the yard(2-1/2 acres) that is pipe fence and cattle panel so I don't have to worry about them leaving the country if they chose to.
