My friends Aussie shepherd had a tumor, which made his nose bleed, it also made him sneeze and bang his nose on the floor, he was 12, the vet said he was too old to operate on, and gave him tablets to control the bleeding, it didn't stop them all together but helped control them. When it got all too much and he went down hill fast he was pts. Sorry this is so negative, hope someone has a more positive story for you.
