Heavy Duty Boundary Flags can be used for any brand of underground pet fence. Boundary Flags are to be used as a visual aid for your pet to help them learn the boundary you've determined for them.
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.

My very strong labs needed to really see these flags..in the woods..and the surrounding acre of fenced land.....these are taller and very strong...would advise on adding these flags to your ivisable fence.....

Wire means they can penetrate our hard clay soil. The flags with the kit were useless plastic that would not go in the soil.

Easy to place flags for boundaries and training dog for invisible fencing.
