My dog's anal cyst is getting bigger after vet injection. What now?

It could be that Benjamin has a cyst in that area, which is why the vet says it's nothing to worry about. Cysts form when a sebaceous gland in the skin is blocked and there is a build up of oil. They are benign, but if it's getting bigger, then it needs to be drained sterilely. You can take Benjamin back into your vet to have it seen again since it's getting bigger, or you can take him into another vet for a second opinion.

I am sorry to hear that! It may be that the infection is still going on - you may need a longer course of the antibiotic or perhaps a different one. I would recommend having them expressed again to see if there is still debris present. I would also want to double check and make sure there is not a mass present in the area:( You can ask for a biopsy to be done if the lump seems unrelated to the infection. I hope this helps and that it is nothing more than a persistent infection!

This could be a seroma from an injury, a cyst, abscess or a tumor. Cysts and abscesses need to be drained by a vet. If your vet suspects a tumor, he will do a fine needle aspirate to determine whether it is a harmless lipoma, which does not need to be removed unless it is ulcerating or bothers the dog due to its location or size, or another tumor that needs to be removed. Please make an appointment with your veterinarian for an exam of the mass.

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.

I don't think you should be worried at this point. There is a good chance it will clear up with the antibiotics and anti-inflammatory. Sometimes the infection can be harder to treat and the gland may need to be infused with an antibiotic. Give the medications as directed and monitor for improvement. Your vet can recheck her in 7-10 days to see if the infection is resolving.

It does happen that cysts can refill, and if that happens it is recommended to have it removed surgically. It could be that it's starting to refill again, and you can ask your vet about having it removed surgically.

Cysts can be left alone if they aren't getting bigger or bothering the dog, but if the number and size of these have increased, then I would take Mimi into another vet for a second opinion. In this case, it might be a good idea to have them surgically removed. I hope this helps!
