This wireless boundary allows you to create a secure barrier around your yard to protect your paw-tners without having to dig or bury wires!
You can adjust the circular boundary range up to ¾ acre (22-105 ft in all directions) from where the indoor transmitter is placed.
The easy-to-read LCD display shows you how far your dog’s play area expands. It also has warning indicators to let you know if there is an error with the wireless fence system.
This portable system is paw-fect for camping, vacation homes, or anywhere you travel with access to an outlet.
The wireless fence system comes with 1 waterproof, rechargeable receiver collar that comfortably fits dogs who weigh 5 lbs. or more, and it adjusts to fit neck sizes 6-28 in.
