Dresden is a lucky girl to have such a smart mom! Getting her used to the "routine" prior to surgery can do nothing but help her.
Here's a link to Bite Not collars -
http://www.vetamerica.com/index.asp?...ite+Not+collar - I looked for a Canadian site, but didn't come up with one. I bought a full 16oz. of Goodwinol from this company but in the end, wasn't able to use it, and they took it back and gave me a very prompt full refund, so I can vouch for the company. You can also fashion your own, using a piece of medium weight flexible-but-stiffish plastic or corrugated cardboard cut to size and wrapped in a towel - then fastened with duct tape.
I'd also set up an x-pen wherever you happen to be, so she can still be with you, and that is something you can do now, too. I know everyone uses crates during recovery, but it sure seems to me it would be hard, not to mention painful, for a dog to turn around in there, especially during the first days after the surgery. I'd be tempted to create a flow-through crate with a door at each end myself!
Here's wishing Dresden a successful surgery, no bouncing off the walls, and much patience for you, LOL!
