Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. Based on its appearance, this is most likely a benign sebaceous adenoma. 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. I am really hoping for something benign. Good luck and have a good one!

    These appear like little sebaceous adenomas, but could be a wart. I'd have to examine them in-person to be more certain. These are harmless and may regress without any treatment, but usually they require surgical removal. For more information about these types of masses, I recommend you read the information at the link below. https://vcahospitals.com/know-your-pet/skin-sebaceous-gland-tumors I hope that helps and all is well with your dog.
