Purchase includes a bundle of 100 DogWatch® Yard Flags to be used for marking the hidden fence boundary around your property. Each flag should be positioned approximately 1 foot beyond (farther out) from the point where the collar-receiver activates, and roughly 6 feet apart.
Note: One bundle is sufficient to flag a one-half acre sized property.
