Any abnormal swelling should be checked by your vet. It could be one of any number of things: -cyst -abscess -tumor, malignant -tumor, benign Even though it doesn’t seem to be bothering him you should have him checked by your vet.

    From the pictures you have sent the "bump" appears to be a skin growth. There are several types off masses that can grow in the skin of dogs such as cysts and lipomas. Some are benign and some are malignant, so careful observation is important, as well as having a vet examine it if you are concerned. . Since you only just noticed the lump, I would continue to monitor it for growth, ulceration, changes in texture or color. Measure the mass with a ruler so you can compare its growth in a couple weeks time. Rapidly growing masses are more concerning. I hope that this answer was helpful and more importantly that Yiur dog feels better soon. Warmest regards to you both.
