I suggest a fence. That will protect your dogs from outside predators also. Let them run free when you can watch them.

Neighbors on either side of me used to be the best of friends. One tries to keep his 2 dogs fenced, but they get out sometimes. The other decided on a large flock of free range chickens in the past year. (Dog owner has 3 acres, the chicken farmer 5 acres).

Now the dogs have had fresh "Col Sanders" a few times, the neighbors no longer speak.
