my dog is ill and I'm unaware of what her illness is

I have two dogs that got in a fight over food. One bit the other on the nose. Now the dogs whole nose is swelling and i think she could have possibly retracted heartworn disease. Now not only she is bleeding and swelling in that one place on her nose, she is also bleeding above both eye brows, she has had no contact with my other dog and i have no clue as to why she is bleeding, so if can help any please email me at sshoe333@yahoo.com Thanks!
