underground dog fence

I have a very hyper dog and was unsure how effective the fence would work for my dog.For the most part it has worked and it was easy to train my dog.I got the one wtih the rechargable collar so I didn't have to keep buying batteries so that part is very nice.I thought that I would try to save moneyso I installed it my self this took a lot of time, you would think that there is a tool out there to make this easier so I didn't have to tear my yard up.The most dissippointing part is that I had called and asked several questions to Innotek about the installiation and I was mis-informed with some information and had to dosome of the fence over agan.I was unable to make the fence go all the way around the house unless I cut through my pavement whice is what I was mis-informed about.But overall it keeps my dog safe and sound in my own yard.
