My 7-year-old dog has a red growth on his penis. Is it serious?

Thanks for using Petco Pet Education Center, formerly Petcoach! That area definitely looks like it needs to be removed. It likely has a poor blood supply and healing can be difficult. I recommend having it removed and have it sent to a pathologist to determine what it is. There is no way to know just by looking at it. I would see if you can move your vet appointment up to have the mass looked at sooner. When the skin is ulcerated like that, most pets won't leave it alone and it can get worse. I'm the meantime, you can wash it with a mild soap and water. Good luck and kisses to Jacks!

That looks like a tumor on Zzzz. Any red, raised masses need to be checked out and aspirated by your veterinarian. While several benign tumors can looks this way, there is a maliganant tumor called a Mast Cell Tumor which can also look like this. Aspirating the mass is the only way to know if it is cancerous and needs to be removed. Also keep your pet from licking at it as this could lead to infection. An Elizabethan collar worn at all times will help. I hope this is helpful and please feel free to post any additional questions.

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing what it is just based on its appearance. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. This is not going to away on its own and needs attention. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!

This growth needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take Marshall to the vet, they will perform a fine needle aspiration on the growth and send it to the lab for analysis. when the result comes, the vet will advise what needs to be done according to the diagnosis.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Thank you for the picture, that is more helpful. The lump doesn't look infected or like a wound, however these are still possible. The lump looks like it could be a bit of a blocked gland, a cyst, an abnormal wart, or a tumor is always possible as well as some tumors, especially Mast Cell tumors, can look like anything. I would recommend monitoring it for now, if it is bleeding, growing (or growing and shrinking), bothering Bogart (he is chewing/scratching at it), or if there is any discharge, then I would get it checked right away. Otherwise, I would wait a few weeks and see if it goes away on it's own. If it doesn't go away in a few weeks, then I would recommend having it removed by your vet and sent away for histopathology. Your vet might do an "FNA" (fine needle aspirate) prior to removing it to determine what it is. Best of luck with Bogart!

You can cleanse it with a mild soap (i.e. Dove) and warm water and then apply a very thin layer of Neosporin to it twice a day. Monitor it to see if it resolves on its own within the next 3-7 days. If it bothers Chico at any point, then it is best to get it seen by your veterinarian for further testing. However if this is just an inflammatory response then it should resolve on its own within a week. If not, then it may need to be aspirated or biopsied to determine what it is and how we need to go about treating it. I hope everything works out ok for Chico.

Hello there and thank you for your post! From the pictures you have posted, it the red blood blister like mass you are seeing is most likely what we call a hemangioma, which is typically benign. However, hemangiomas can turn into hemangiosarcomas that are cancerous. I would recommend having this removed if possible to prevent this from progressing. If Gizmo does not do well at the vet, you can ask if they can provide you with an anti-anxiety medication / sedative to administer prior to an appointment to get this looked at. I hope this helps! Please let me know if you have any other questions or concerns. I am also available via consultation if needed.
