I agree with what lv4dogs said...put up all things like food, toys, bones, etc. There's not much you can do in a short period of time to work with such ingrained behavior issues. I'd even go so far as to muzzle a dog that was endangering my own dog. I wouldn't leave them together unsupervised for any length of time, not even a minute or two. I would crate the poodle and/or Fenway. Or simply keep Fenway upstairs and the poodle downstairs or vice versa. Good luck! And, I certainly wouldn't offer to watch the poodle again.
