Our rescue cattle dog is pretty good but sometimes she gets head strong and goes beyond the boundaries we have set for her. She will come back but it only will take once if she ever gets all the way out to the highway. Anyone have and can recommend a wireless dog fence. Looks like the PetSafe at $259.99 is pretty popular, or at least available.
