Have you ever noticed the unique patterns on top of bearded dragon heads? I've owned a couple beardies before and I've never come across a bearded dragon with similar head patterns.
Man, what? i never trim my guys nails.
Should I? He's only a year old.
Yes. Sometimes beardies are active enough that they wear them down themselves, but in the case of OP image those nails definitely need a trim.
Check Google for tutorial on how to go about it. It will have pictures of what is too long and what length to trim to.
