651-00002 - PetSafe Boundary Flags Bundle of 50

This pack of an additional 50 Boundary Flags are useful for reinforcing training or expanding containment area. Place flags approximately 10 feet apart to remind your pet of his off-limits area. Between days 15 and 30, you will be monitoring your pet's progress. After you are satisfied your pet's training is complete, remove every other Boundary Flag every 4 days until all flags are removed. In about a month, your lawn will be free of training flags and your pet will know his limits.
