This looks like a mass not a bite. I recommend an exam. They can feel it and if it’s a mass can aspirate some cells to see if it’s benign or malignant. It may also be a sebaceous cyst. Since it looks to be only in the skin it can be surgically removed easily. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Titan.
