So I was brushing Parker last night and was feeling around and checking his skin out and found a ball the size of a pea on his right thigh. I would say about where he got his last set of shots. This was about 2 weeks ago. Is that normal for him to have a ball like that on him, I am so scared now, should I take him into the vet? I squeezed it to see if it caused any discomfort and he just looked at me like "mom why are you poking at me" It didn't effect him at all.
