I have a 2 year old male bearded dragon. I got him about a year ago from a co-worker. When I got him one of his back feet had 3 toes that looked like skin was covering them. I thought he was finishing shedding. A few weeks later the foot fell off right by the joint. It didn’t bleed at all. It didn’t seem to bother him. After a few weeks it looked like the nub was growing but it was darker than the rest of his skin. He has had it for months. Today the nub fell off. It was bleeding a little. I soaked him in the tub in warm water to clean it and put neosporin on it. Is there anything else I should do? I am worried about him.
