I got this bearded dragon about 5 months ago? Maybe more. From a guy on Craigslist via my grandma. I don't know anything of past husbandry or health issues. He's about a year old. He has a dark spot next to his right back leg and similar spots have shown up within the past two months. I thought it was dirt, but when I have given him baths nothing's come off. He's shed 2-3 times and it hasn't gone away. I can't afford a herp vet at the moment and I'm really scared.
