Re: A lot of fence wire about 4ft high to attach to my timber fence to keep the dogs
Don't know about the chicken wire. I recently built a bit of a run for my two pure bred mongrels, and they keep busting out. The wire is pretty brittle if chewed on for a while, and snaps real easy, giving them an opportunity to expand the hole.
I would recommend something a little heavier guage, especially if its going to be in place for a while.
Plasticoated chain link may be the one, and as said previously, any decent agri or builders providers should have it.
Cheaper than the electric shock collars as well I would have thought.
