After the dog has been trained and really understands the boundaries, wait a month, then start removing the flags. First, remove every second flag. Then wait a week, and remove every second remaining flag. Wait another week and remove all the remaining flags.
Hear what our customers are saying about the Dog Fence DIY difference:
If you're even a little bit handy, don't pay a 'professional' $1,000+ to do this. I'm not exactly Bob Villa around the house, but between the information on the DIY web site and the DVD which came with the Innotek IUC-4100, I felt well prepared for the installation process. Sure enough, in one afternoon I got the fence up and running with no issues...to the muted amazement of my wife and neighbors.
Perhaps our Vizla is a quick learner, but I was pleasantly surprised at how short and simple the training process was with him. To this day, he has only been 'shocked' once and has never left the yard. Actually, we hardly ever put the collar on him anymore since he won't stray past the boundaries anyhow.
We also discovered an added benefit of the fence system. Along with our fence, we purchased a couple Innotek Indoor Zone transmitters, and placed them in some rooms we wanted the dog to stay out of (at the time he was a new puppy and not house broken yet). Then I cut some old tennis balls in half, pierced a small hole at the top, and then pushed a training boundary flag into each one. Next, I placed these tennis ball / flags by the entrance to the rooms we wanted the dog to avoid. This inside process worked just as well as the exterior fence. After a little while, I removed the flags, but the dog still knows not to go into the dining room or living room. This was infinitely easier than trying to erect and step over flimsy gates As an added benefit, we can now just place one ball / flag by something (eg: a shoe rack) and the dog knows to stay away from it.
