Petsafe Guardian GPS Dog Fence User Manual page 12

• Opposing lines of digital fence posts must be at least
35 feet away from one another, to avoid creating areas
too narrow for your dog to pass through without being
corrected.
• If a physical fence exists along the desired boundary,
place the digital fence posts at least 10 feet outside of
the physical fence. This allows your dog the most usable
area inside the physical fence.
