Why is my dog licking a bump on her rear after allergy meds?

Updated On September 23rd, 2025

Pet's info: Dog | Blue Heeler | Female | spayed | 43 lbs

I noticed this bump on my dog's hind end, of course after vet hours today. She has been licking the area a lot and scratching the last couple of weeks. I took her in to vet 1 1/2 wk ago. They gave her Cytopoint injection. Apoquel wasn't helping much. Any thoughts what this bump is?

It is hard to tell from the picture but it maybe the start of a pustule which can be a sign of a skin infection. It may also be a cyst or sebaceous adenoma or wart as they have a similar looking characteristic. Since she has been through Cytopoint and Apoquel with out much relief, she may benefit from a dermatologist to get intradermal allergy testing. Your vet can check that spot to be sure what it is and set up a referral for the skin if you wish to pursue that route
