Petsafe Guardian GPS Add-A-Dog Collar

Add a dog to your Guardian GPS Dog Fence — up to 8 pets per system

The Guardian GPS Add-A-Dog Collar lets you expand your Guardian GPS Dog Fence to cover the whole pack without buying a second system. Each collar pairs independently to the same GPS boundary you’ve already set up in the My PetSafe app. You manage every collar from the app — correction levels, battery life, and settings are customizable per dog. One system, up to 8 dogs.

The collar uses PetSafe’s AccuGuard technology, which layers GPS satellite data, real-time motion detection, and AI to predict your dog’s movement and deliver a warning before they reach the boundary line — not just when they cross it. This is what separates it from simpler GPS fence systems that only react after the boundary is breached. Correction is your choice: tone and vibration for the training phase, or up to 10 levels of static correction once the boundary is established.

Battery lasts up to 5 days on a single charge and recharges fully in 2 hours. Completely waterproof. Minimum age 6 months.

Compatibility: Works only with the Guardian GPS Dog Fence (PIF00-17933) and the Guardian GPS Connected Customizable Fence (PIF00-17777). Not compatible with any other PetSafe wireless or underground fence system. Requires a property larger than ¾ acre for proper GPS boundary function.
