Dogs love to roam around; it's part of their inquisitive nature! Some dogs can get a bit carried away and the possibility of the dog running away can be a bit scary for owners. At Dog Gear Etc, we feature fence systems that allow you to create a predetermined area and boundary where your dog cannot go past. Our dog gps collars can be activated in a few modes like warning tones, vibration, and 15 levels of static shock correction. This removes the need for a physical fence. You'll be able to rest knowing your dog is safe where you left it!
