If you check at Home Depot (and probably Lowes) you'll find that there are attachments and elements of chain link fences for sale that you might want to look into. Metal corner posts, for example, and there are things to stabilize the bottom and patch any breaks, etc. Will the dogs tend to try to dig their way out? If not, no problem, but if they want to, then you need to stabilize the bottom of the fence some. And be sure to use lots of the wire ties along the top rail (if you don't use a top rail then the fence is just a big sheet of wire cloth they can go over the top of very easily).
