I have a problem with a 6 yr old Aussie.
I am hoping someone can give me some good advice. Kathy Diamond Davis?
We have a big yard, it was all fenced in with 4 ft fence, one side is a 6 ft privacy fence.
The side by the street had to be lowered to 3 feet. Of course the dog can and does go over it.
She runs the fence then will stop and put her feet on it and pull herself over.

How can I train her not to do this.
Putting her on a leash or a long line does not work. If you take her out on a lead or a long line she doesn't even bark at anything.
She will totally ignore anything or anyone going by the fence.
We have a 25 ft and 35 ft long line. We can sit outside for over an hr and she just walks around or lays down. She'll play ball and play with the other dog, but doesn't show interest in running the fence. But take the lead off and she runs right to it.
Is an invisible fence my only option?
