A lump with hair loss around it could be caused by a number of different things. Buzz may have an abscess due to some type of wound, a localized inflammatory reaction or infection of some kind, or even some type of cyst or skin tumor. I would recommend having the lump checked by a vet when you are able to. He/she may be able to identify it based on its appearance and how it feels, or may recommend a simple test called a fine needle aspirate to find out for sure what it is. Buzz may need antibiotics and anti-inflammatory medication to treat the problem, or the lump may need to be surgically removed.
