American Fence Company Dog Fence...? ?

Dog fence...? ? - american fence company

Well, we had a spring for men, golden retriever, very energetic and if it breaks, and I hated that he was there the whole time.
We have finally able to leave him in the garden and do not leak or anything.
Then he started a little walk. We can not go back to the pen, it was too big for him.
How do we build a cheap but high hurdle big enough? We live in Ireland, I can not buy American companies, and I do not argue with an electric fence.

What do you recommend for Born on the fence? What is the link in the chain? What would be the stronger, firmer and less expensive to build a great wall that can (but must not itself build), built on our own?

Thank you very much
