Should a dog have a good handle before being put in the woods?

This is a subject I was going to bring up, Today I let my 2 females that are 6 months old out of there pen and they ran around the yard. I called and called them with no response, even put food in their bowls and they would not come to me or get in their pen. I have only had the dogs a little while and they have absolutley no handle but have the drive of 10 dogs. They took off threw the woods and did not come back for 2 hours I was pissed and upset at the same time. Looks like a long lead or shock collar before I let them out again. Your question about having a handle on a dog, IMO absolutley manditory to have a handle on your dogs. When they did not listen to my commands I felt like getting rid of them on the spot.
