Raw, sore nose.

Hi there I have a 5 year old Malamute named Mika about a year ago she was attatcked by 2 pitbulls and in the process of her protecting herself her nose which used to be black has been pink ever since (really raw) and continueously keeps cracking and bleeding and she keeps bumping it causing furthur injury. As a result of this injury and her scratching she got an infection in her snout and it travelled to her eyes causing drooping underneath the eyes and a clear discharge and her eyes seem dry and red. I took her to the vet for this and she was on antibiotics and I changed her food from benifil to science diet. She has improved majorly and the infection is gone. However she continueously bumps her nose re-opening her nose wounds and her eyes are still droopy but she is back to her happy self. I have taken her to the vet a bunch of times now and am definatly running low on money for the vet as the bill runs me over $600.00 everytime not that I mind I love my dog but I am wondering if there is anything I can try at home. Please help I love my dog and I would like to see her nose finally get better and her eyes not be so droopy. Also she has almost like dry scalp in her ears and they look sore I am at a loss and would be devistated if she doesnt get better. My poor Mika hopefully you can help
