Hi, new bearded dragon owner here! This might be nothing but better safe than sorry because these dark marks I found on my new baby beardie just doesn't seem to be a part of her scale pattern and no it's not dirt or anything.
Hi Eileen...those are just a couple small spots of skin shed on your cutie-pie. They will come off in time, nothing to worry about. Beardies shed in strange ways, especially when they get bigger.
