Let us know what the vet says.It seems either as swollen or less swollen, so I'd call that progress. Plus the fact that she stands on both feet, runs, walks evenly again, etc. I can only assume it's feeling much better to her. I can't quite tell if her leg might still be a bit warmer than the other.
