The Invisible Fence

Since we got the pup it has been a constant training session. And since we are a little a lot concerned about our new pup getting hit by a car we called in the big guys. Tomorrow there coming to talk to us about having invisible fencing installed in our yard. I am praying it doesn't cost a lot other wise she will only be let out in the back yard, which we have to finish putting up the fence on the north side of our house.  If anyone has had this installed or know anybody who has let me know what they thought of the system.  From what i have heard from homeowners that i clean for they all love it.  But i want peoples honest feed back.  Now us girls are off to go bake some doggie treats, we might be having a doggie social party this weekend. And our guests love my home made treats!
