Started as a tiny lump, gets bigger each year, and bleeds
Expert Answer
From the photo, the dog’s raised lump is considered an abscess or tumor. If it is an abscess, it may come from inflammatory infection. Since it has now ruptured, take the dog to a vet for debridement and drainage.
Because the spot is near the eyelid with many nerves, do not treat it yourself; professional vet care is best, and local anesthesia may be needed first. If the abscess keeps returning, consider whether a tumor is the cause.
My dog's growing bleeding lump near the eye needed the vet's debridement, and they warned against home treatment because of the nerves there. I'd get it looked at and biopsied if needed. Mine's was benign but required proper care, so I'd treat any enlarging bleeding lump seriously, the eyelid location makes self-care dangerous, the vet's the only safe call.
