Bad dog fight and swelling in my dogs throat area?

Is there any major wounds such as bleeding? There could be a clot in the neck if so. Yes get her to a vet asap, remember dogs bites are infectious even to one another. The throat is a tender area and has a major vein running through it. This is the main reason dogs go after one anothers throats. If she is in pain you can give her a asprin if you are not able to seek medical attention, but a vet is a MUST.
