GPS technology has up to 10 feet of accuracy drift. That means your dog's actual boundary could shift 10 feet in any direction and the system has no way to know.
For a large open field? That drift is manageable.
For a typical suburban yard? That 10-foot uncertainty zone covers a significant portion of your usable space and your dog's safety margin.
Dog Guard uses a buried wire system. The boundary is exactly where you set it. Not approximately. Not within 10 feet. Exactly.
Your yard size shouldn't determine whether your dog is actually safe. That's why we've been doing this with wired systems since 1988.
