if these are old wounds that are causing the swelling she most likely has developed an infection from them. Even though they cleaned her up when they found her dog bites can get terribly infected and really need antibiotics to help combat the infection. if you have access to an emergency vet I really suggest not waiting until monday as sepsis can set in quickly from this type of infection. if you do not have access to an emergency clinis you can clean the wounds again using peroxide. once clean soak her leg in a warm epson salt bath to help reduce the swelling and soften the tissue so that if there is a pus pocket under the skin it can open up. the warm water will also help make her a little more comfortable. you will need to soak her leg every eight hours until she sees a vet. after her soak (which should be at least a half an hour long) you will need to alternate between warm and cold compresses every three hours for 15 minutes at a time to help control the swelling. do not use an antibiotic ointment on the wounds as they cause the wound to heal from the outside and if there is infection underneath it will seal in the infection instead of letting it drain. you can give her a Bufferin brand aspirin for pain if you feel she needs it. one tablet every six to eight hours as needed.
I hope this helps. Please let me know if you need further information.
