My yard is 100% fenced in from front to back with padlocks on all of the gates.
It's 4 foot chain link fence. My back yard is an ok size but it has a driveway and my car. My front yard is very large so that is where the dogs are 95% of the time. Sometimes I will unlock the gate that connects the front yard to the back yard and they can run the whole yard.
