I totally sympathise. Our yard isn't fenced and my little dog has no road sense, she will sit in the middle of the road if I let her (of course I don't) so we installed a chain link fence in a small area so she could go out there. I also take her for short walks 3 times a day. I would recommend chain link rather than electric -- more humane! I don't like the idea of leaving her chained unless you are nearby, because a bigger dog could come on your property and attack her and she couldn't get away.
I am very sorry about your other dog. I just read a book called the Dog Listener by Jan Fennell, and basically, it's a humane way of dealing with aggressive dogs by positioning yourself as the alpha dog -- they realise they don't have to be alpha and eventually relax. I recommend it to anyone whose dogs have behavioural problems. it would probably help with Val too, as she will be more obedient.
