We tried an invisible fence for our Kangal Dog because he could jump the existing actual fence. I tried to get through the training part of the fence installation, but A) it wasn’t working (he didn’t react at all to the shocks) and B) I hated the idea of shocking my dog. We built a taller fence instead.
That dog was problematic in so many ways, but I loved him so much. First and last time I’ll ever have a purebred dog, though.
