A Virtual Fence allows you to keep track of where your dog or cat is at all times, and keep them safe. If your dog's in the backyard, you can open the app and check on them. If for any reason they leave the "safe area" you'll be alerted automatically. With Tractive, you can use LIVE Tracking to find them immediately. Physical fences don't alert you if your pet escapes. The Tractive Virtual Fence helps you keep track of your furry family member and keep them safe. It helps you prevent them from ever coming into harm's way.
