What do you expect out of your dogs?

The veteran dogs have to be a little on the rangey side. Our property is pretty big. They have to have a hot nose. Hogs cross all over the property all of the time back and forth between the farm we hunt and neighboring leases so I want them to wind a hog thats pretty close by, not all the way over on the neighbors property. Some bottom is required but not endless bottom. We will go to our dogs when we have to but I like for them all to know how to backtrack. THey MUST be SILENT on track. This is important for them to stay on our yard. If I hear a bark, they had better be looking at the hog. PERIOD! I know that open dogs bay and catch hogs all of the time, but silent is our personal preference.
