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!

My dog has a red, ball-like growth on his penis. Should I be worried?

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!

Should I worry about my dog's skin bump near his penis after grooming?

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. 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. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. While this could be something benign, there is a possibility of it being malignant which is why it needs to be taken care of. I am really hoping for something benign. Good luck and have a good day!

My dog has a bleeding lump on his back. Is it serious and what to do?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Thanks for the pictures! Many skin masses can look the same. Red dermal masses, like this one, can be benign or malignant. Some possibilities are an inflamed sebaceous adenoma, hemangioma, histiocytoma or it could be a Mast Cell Tumor. Since it showed up quickly I would have Oscar seen by your Vet. They can decide if aspirating it (sticking it with a needle and sending the slides to the lab) or removing the mass and sending it for biopsy is best. I hope this helps and I wish you and Oscar the best!

My dog has a red lump on his genitals and hates the vet. What to do?

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.

My dog has a red lump near his penis and keeps licking. Is it serious?

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.

My dog has a red lump or blister near his anus. Is it serious?

It's a little difficult to tell from your picture alone - being able to examine and touch a lump in person makes it much easier to determine what it is. This could be a skin tumor, a small abscess or inflammatory nodule, or a lesion from something like contact hypersensitivity. I would recommend having this lump examined by your veterinarian since it looks red and possibly like there is discharge. If he is licking or chewing at the lump you should put an e-collar on him until you can see a veterinarian. They may know what it is after being able to examine it or may recommend taking an aspirate sample using a small needle to look for cells under the microscope.

My dog has a bleeding growth near his penis that burst. Is it serious?

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!
