I'm sorry that your question wasn't answered in a timely manner. Thank you for the photos. There's a considerable amount of erythema - reddening - around a black lobulated skin tumor which is worrisome for melanoma or another aggressive and hyperpigmented skin neoplasm. I would need to shave that area to get a better look at it and I encourage your having Stewie's vet do just that and then advise. I can't rule out an envenomation - flying insect, spider - that happened to occur where that neoplasm is present and that would be the best scenario of all.

Please respond with further questions or concerns if you wish.
