I gave in and gave Rudy some rimadyl yesterday. I hate that stuff, but the arnica just wasn't strong enough. On one hand pain is good in that she was staying fairly calm and not moving around too much, but it's terrible watching your dog in pain. I ordered some traumeel for her, it's a homeopathic blend of several things that hopefully will help her and some glycoflex III for the whole pack. I'm going to contact Maria from annisage to see if she has any experience with this and see if she can work on Rudy a bit.
She does seem better today, but keeping her off the stairs is quite the challenge, as is not doing anything with her! I'm going to try giving her and Willy marrow bones and sneaking the others out to the park for a while. Willy and Rudy just love each other and Willy really doesn't care about going to the park unless it's in the 70s and sunny!
