Just my opinion but Goldens don't make for a good outside dog. They actually believe that they are people and will want to be inside with you. Sitting on your couch, eating at your table, sleeping in your bed, etc... I have a Golden and when I got him I knew he would be an inside dog. You may want a different breed for outdoors or maybe one with short hair and hypoallergenic for indoors.

Sorry, I don't know much about invisible fences but as someone mentioned it will be all about training. By the way, most dogs don't like to listen until they're at least 1.5 years. That's the age when all the earlier training makes sense to them. My dog is 11 but even when he was younger I could leave him outside (front of the house on cul de sac) for long periods and he will still be on my property.

Whatever you choose, good luck and take some photos.
