I got my puppy almost 2 weeks ago. I noticed that he has a small bump on the side of his front foot. It looks almost like a pimple, except a little bigger. I told the vet and he said it's probably nothing to worry about. He said it was a nodule. What is a nodule does anybody know? Are certain breeds more prone to getting them then others (he's a pit/american bulldog mix). Will this effect him in anyway either now or when he's old? I don't know what it is and I am just sort of curious.
