My dog's penis is swollen, bleeding, and has an open sore. What to do?

Updated On September 23rd, 2025

I don't know what's wrong with my dog. He was looking sad when I came home. I noticed drops of blood on the floor. And I started to check him out and noticed his penis is swollen and has a open wound. His testicles are not swollen. Only his penis. I don't know what to do.

Poor guy! I'm sorry to hear that's happening. Looking at the pictures, and depending on his age, I would be concerned it may actually be a tumor that has broken open. (This is more likely if he is an older guy). It may also be that there was some trauma, or was a small trauma that became an abscess or infection. Regardless of the cause, call your vet and get him in as soon as you can. At the very least, your vet can give you some medication to make him more comfortable. There is no way to effectively bandage this area at home, as we don't want to block his penis, because if urine collected in a bandage it would only make things worse. Please refrain from giving him any over the counter pain medication until you see your vet. Best of luck to you both. Thanks for asking Petco Pet Education Center, formerly Petcoach!
