The bump you are seeing could be a mass, or it could be a skin lesion caused by bacterial, parasitic or fungal infection, dietary or environmental allergies or sensitivities, or could be a combination of the above. I recommend making an appointment to have Bowser seen by your veterinarian to help determine the cause of the bump you’ve noticed and to make sure it is treated appropriately. The vet will likely want to look at a sample from the area under the microscope to determine what is causing the bump and to provide treatment. If you notice the bump is oozing or becoming ulcerated, if it appears to be causing Bowser pain (if you notice him licking at the area or limping) then I recommend calling your vet right away. In the meantime you can put an e-collar (cone) on Bowser to help reduce the risk of him licking at the area, as this can reduce the risk of infection. With Bowser's young age, it is not very likely that he would have a malignant mass, but it is a good idea to get it checked just in case, just as it is with any mass. Good luck!

    Pets can get many types of lumps and bumps. Most of these tumors will be benign but some will be malignant and you can't tell by looks. Here is a helpful link discussing the various types of skin masses in general: https://www.petcoach.co/article/lumps-and-bumps-on-your-pet/ I do recommend to have it checked out to be safe. The doctor may recommend to aspirate the mass to examine the cells under a microscope. That is one of the best ways to know what it is and if further action is needed. Hopefully it's nothing serious.
