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.
