How do I keep my Border Collie inside our invisible fence? Dog Breed Discussions
My Border Collie aged 2 was trained to stay inside our invisible fence a year ago but the last few weeks she just runs out and takes the shock. It's still the same power and frequency, she gets plenty of attention (frisbees, walks, etc) but she still bolts when a person is walking by. The mailman is very upset!
