Hi, my daughter was bitten by a dog 1 week ago. She had 12 stitches put in 6 days ago, and I had to bring her in 2 days ago for infection. The area around some of the stitches is still a little red, not as much as it was, but her arm is still leaking a yellowish-reddish substance. I am concerned it is still infected...could it be serous fluid or exudate, or another infection?
