I noticed small red spots on my beardies belly yesterday and I'm pretty worried. I cleaned out his home, and found nothing growing in it, and I gave him a bath and tried brushing the spots off, but none came off.
He's eating and behaving normally, and is also shedding at the moment, with no other problems.
Should I be worried? I'll try seeing if I can get him to the vet if they don't clear up in a week or so, but I wanted to know if there's anything I can do.

Looks like dirt to me, he's either been sitting on his salad (they will do that sometimes - like they are guarding it or maybe because it's soft and cool) or he's crawled over or laid on his poo.

No biggy.... if they are stains , they'll disappear with the next shed.
