Thanks Wendy!! Yes I love them being able to run around and get their enegery out!! Then they are so much better inside! I absolutely love your avatar of Daisy! It crakcs me up everytime I see it!
Rachel, I was afraid of the same thing and I can't believe how good it works. We have jackrabbits running around here and the neighbors dogs tease mine but they still won't pass it. If there is something they want to chase they run as far as they can and when they reach the end of the boundary their brakes go on, lol and then they sit there and wine! It's pretty cool!!
