Hello and welcome to Petco Pet Education Center, formerly Petcoach. Thank you for the picture, that is more helpful. The lump doesn't look infected or like a wound, however these are still possible. The lump looks like it could be a bit of a blocked gland, a cyst, an abnormal wart, or a tumor is always possible as well as some tumors, especially Mast Cell tumors, can look like anything. I would recommend monitoring it for now, if it is bleeding, growing (or growing and shrinking), bothering Bogart (he is chewing/scratching at it), or if there is any discharge, then I would get it checked right away. Otherwise, I would wait a few weeks and see if it goes away on it's own. If it doesn't go away in a few weeks, then I would recommend having it removed by your vet and sent away for histopathology. Your vet might do an "FNA" (fine needle aspirate) prior to removing it to determine what it is. Best of luck with Bogart!
