My dog has a sore paw, limping, and a bump under his nail. What's wrong?

Have a 3yr old GSD with a small bump under one nail. Seemed sore yesterday and was limping and licking, today was able to touch his paw and check ... looks almost a bit like dirt but doesn't come off... Wondering if something I need to worry about?

It is very difficult to tell from these photos, it is possible that your dog's toe nail became slightly torn/detached from the underlying nail bed and you are seeing the separation here. We can, however, occasionally see nail bed tumors. I would recommend a visit with your vet to better examine the area. If it is a loose toenail they may need to trim it back to make it more comfortable until it grows back in normally. This can be very tough to do at home because often these guys are painful so trimming the nail back can be really difficult without skilled help!
