Pet Fence Training: Step Four

Introducing Off Leash
Now start to allow your dog to be in the yard off leash. Keep the sessions short and supervised at first, but if the dog observes the boundary then extend the sessions, and start to go inside for short periods and leave the dog unsupervised for a few minutes. Peak through your window and see what happens.

If you get any breakouts, then you will need to do some more training on step 2.
