You have to be a little careful about putting ointments down inside of wounds. The body has to evacuate it back out, since it can't be absorbed. This is not the kind of wound I would use silvadene on.
It's not unusual at all to be able to smell a wound. Often when we bandage injuries will leave the bandage on for three or four days before changing it, to minimize disrupting the newly growing granulation tissue, and they get pretty stinky.
While you can use diluted betadine to flush wounds, I think what you're doing already is fine. When you do your bandage changes put a warm Epsom salt compress on there to soak out discharges, improve blood supply, and help her be more comfortable.
