Thanks for your feedback Holly!
Young dogs often need time to develop impulse control and during this time it’s really important to ensure they are safe, just in case their impulses lead them into harm’s way. I have seen many dogs who have managed to outsmart electric fences and so I prefer to have a more solid structure in place. It may be really impractical to fence your entire yard but it may be possible to construct a smaller space for your dog to remain in when they are outside unsupervised….just to help keep them safe. Working on recall will also help teach your dog where your property boundary is, but consistency is key here so when outside in an open space they would need to be supervised. All the Best, Doggy Dan
