Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 4 months and 23 days old | 35 lbs

My dog continues to get bumps under is jaw, neck and onto the sides of his face. This bumps contain a puss / watery fluid. Sometimes blood. When I find them they appear in clusters and some have already popped leaving it dry. I have popped one myself. Can appear as bumps under the skin and some can appear on top showing a white head. He has been treated with antibiotics before. They still won't go away.

There is usually something about the area that is inviting for infection. Often, it's either due to an allergy, or the skin being excessively moist. Finding the specific cause is important, but often difficult. Watch for any particular habits he has where this area has contact with plants or other materials. Also check that he is not having excessive moisture under the chin throughout the day. For now, I recommend washing the area with a medicated shampoo containing chlorhexidine or benzoyl peroxide (these can be found at the pet store or veterinary clinic). Wash for at-least 10 minutes once a day and rinse with cool water. This should help to clear-up the infection and prevent future infections. However, you'll have to do this until the underlying cause is found and eliminated. If you are not able to find the cause relatively soon, then you should have him reexamined by the vet. We have various tests that we can run to help identify the cause. Also, the infection may need to be specifically identified and treated with antibiotics for longer in order to completely eliminate it. I hope that helps and Copper gets better soon.
