Easiest way to fight hell hounds is at Nieve's Slayer Cave, bring your cannon, and if you dont want o bring food then use Guthans Gear for its heal. This may be a slow way of killing Hellhounds though..
I believe that in order to better your knowledge base, it takes a lot of failing in order to succeed. I don't consider anything a failure as long as you get back up and you learn from your own mistakes. Unknown
