My dog has a bump on his penis. Is it a bug bite or something serious?

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!

Hello, thank you for using PetCoach. It is very difficult to say what a lump could be without feeling it. My best guess is that this is a sebaceous cyst which is benign. So, yes, you should take him to your vet for an exam. It is not an emergency; just try to get him an appointment in the next week or so.

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.

Hello. Thank you for using Petco Pet Education Center, formerly Petcoach. It is very difficult for me to comment without at least seeing a photo of what you are referring to. Can you please post again with some photos? Is the hole in the prepuce (sheath) that holds the penis or is the hole in the penis itself? Thank you.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. The picture you posted is really not clear, so please re-send us the question with more pictures, ideally from a longer distance so we can see better what is going on with Hadley.

Thank you for using Petco Pet Education Center, formerly Petcoach! While this may be a bug bite, the texture appears slightly rough in the photo, so this may be a growth or mass. It is concerning that is has been present for a week, as a bug bite would have likely resolved by now. I recommend having Layla seen by a vet as soon as possible, especially because the area is red and near the mammary chain. Your vet can either remove the lump or take a small sample to determine exactly what it is. I hope this helps and that all is well!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. From the pictures, I suspect that what you are seeing is a insect bite or pustule. I would recommend monitoring it for now and if it worsens, becomes much larger or does not go away, I would recommend having the veterinarian recheck Maisy so that the most appropriate diagnostic and treatment recommendations can be made. You can apply a spray such as Malacetic conditioning spray to the area, which can be found online and do this twice daily until it resolves. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
