The short answer
Plan on two to four weeks of short daily sessions: put out boundary flags, walk your dog on lead and reward it for turning back at the warning tone, and only then add distractions. Use the lowest correction level that works, or tone and vibration only where the system allows. Welfare groups advise reward-based methods and a qualified trainer.
Week by week
- Week 1: flags out, collar on with correction off or tone-only; walk on lead and reward turning back at the tone.
- Week 2: short sessions with correction at the lowest level; keep the leash on.
- Week 3: add mild distractions such as a toy outside the boundary.
- Week 4: supervised off-lead time; keep flags up a few more weeks.
Signs to stop
- Your dog won't go into the yard or freezes.
- Repeated corrections in one session.
- Fear of the flags or collar.
If you see these, pause and get help from a qualified trainer.
