Hi again Roni!
This is regarding your other question. Yes, it is normal for pus to exit during treatment. In my experience, when I began the treatment the discharge was initially pinkish to reddish and a little bit watery. As I continued treatment the discharge became whitish and less watery. Then when the dog is nearly cured the discharge became clear in appearance. And finally, the discharge will completely disappear. You will know that your dog is cured when there is no more discharge and your dog will have a voracious appetite. Just to be sure, continue treatment for at least 2 weeks more just to make sure that all bacteria in your dog's uterus is already cleared up.
