I have a German Shepherd puppy (4 Months old). There are some wart like things (maybe warts) on my dog's legs. They are on every leg. Rear Legs have it in back of the joints. There are 3-4 of those things on each leg. When touched, there are multiple lumps under the skin. Also some white skin on the top of the wart, maybe you can see it the photo. I think it hurts him when I touch that. He often scratches and bites himself.

Please help me identifying what it is. Is it allergy, infection or something else? I will take him to the vet as soon as possible, but it would be great help if I knew what is wrong. I am really worried. Is there something I can do to stop it?
