My wife and I have just purchased an 8 acre property(cheap!!) in upstate New York. I want to install dog doors so I don't have to get up and let the dogs out every minute. Of the 8 acres, 2 acres are lawn area and the rest is brush and forest. I don't want to fence in the yard but I want the dogs to come and go as they please. The problem is I don't want the dogs to run away, especially chasing a deer or something. I really don't want to install invisible fence because this is expensive and sometimes I want to take the dogs beyond the perimeter of the lawn. Can I train my dogs to stay close to the house? One of the dogs is a male. I have noticed that the neighbors (few and far between) have their dogs loose and they seem to stay close to their homes. Please help with any advise you can offer!
