Pet's info: Dog | Soft Coated Wheaten Terrier | Female | spayed | 13 years old | 30 lbs
My 13 year old Wheaten has had a large sebaceous cyst, about 4 cm in diameter. It ruptured and a few days ago, had no real odor, and clear fluid with sebum granules drained from it. There is no apparent infection. We have been flushing it with saline, pressing to expel any liquid and lingering sebum within it, after which we are applying antibiotic ointment, then covering it with sterile gauze and an ace bandage. Do you think this treatment will be adequate ?

The problems with cysts is that they open reoccur, and typically need to be removed surgically. In addition, removing the fluid from a cyst should be done in a sterile manner, and I would be concerned that you may accidentally be introducing infection into the cyst yourself by pressing on it. I would take Akkiko into the vet first thing in the morning. The vet can drain any remaining fluid with a sterile needle and syringe, and can discuss removing it with you. There is also the chance it could be a malignant adenocarcinoma, so it is a good idea to have the vet biopsy it just to make sure it is benign.
