Found a small raised red bumo under dogs chin near neck. Nothing but blood comes out. It looks to be a wart or possibly a histiocytoma since he's roughly 6 months old

It is possible that this bump on Howl is only a wart or a histiocytoma, but it could also be a cyst. Without seeing him in person, I can't say for certain, so I would have him seen by a vet in the next few days to have the bump examined. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the bump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the bump is diagnosed, the vet can let you know if any treatment is needed for it. I hope this helps :-)

It could definitely be a histiocytoma or wart since he is young. The only way to know for sure is to have your vet examine him and do a fine needle aspirate. Once diagnosed, your vet can determine if treatment is needed. If it is a histiocytoma or wart it should regress with no treatment in a few months. It could also be an infection and your vet could prescribe an antibiotic to treat.

This looks like a growth. It could be benign like a histiocytoma but it could also be malignant like a mast cell tumor. Since it has been there for a month and it is bleeding, I would definitely have your vet look at it. Your vet will be able to help determine what type of mass it is and whether or not it needs to be surgically removed. They will also be able to tell whether or not it is infected and if he needs any oral antibiotics. I would also not let him rub it so you may need to put a cone collar on him to prevent this and help it heal and stop bleeding. I hope this helps.
