Is there a limit to the number, location, or size of Halo Fences I can create?

You can create an unlimited number of fences in your Halo app depending on your plan, and they can be created anywhere in the world. If you intend to go to a zero-coverage area, you can set up your Halo Fences before you leave, and it will work seamlessly. You can edit any fence, at any time (just be sure to practice this new boundary with your dog!). Each fence needs to include a minimum of 30ft x 30ft for your dog to roam safely, and can accommodate a maximum of over one thousand square miles.
