Evcvet, have a question for you. My old lab has developed a bump on the wrist of his right front paw. It is raised about 1/4 inch and has all the hair rubbed off the bump is about the size of a fingernail. It does not seem to bother him though I did see him licking it yesterday after I discovered it. Should I be concerned about it? Is there anything I can do ie lance it etc?
