It may be an abscess or mass. A visit to your veterinarian would be recommended. A fine needle aspirate can be done in the clinic to collect samples for pathology. If it is an abscess, it may be drained and antibiotics dispensed. If it a mass, benign or malignant, you can discuss treatment options with your veterinarian.

    Thank you for using Petco Pet Education Center, formerly Petcoach! What you are describing can be an abscess, a growth or mass, or a deep wound. I would be happy to take a look at a photo to give you a better idea of what may be going on. You can also have Gus seen by a vet as he may need antibiotics or pain medication. I hope all is well!
