Can one trim a bearded dragon's nails?

Yes you can. But make sure that when you do it you use a sharp pair of nail clippers (either human or dog clippers) if they are an old pair and aren't very sharp anymore they will just crush the nail instead of cut it. Also, more sure you are not too close to the blood vessel inside the nail. If you cut this, it is painful and will bleed. If you have cut a dogs nails before and know how to do it, then you can cut a breadies nails. If you haven't and you are nervous about doing it, ask someone in your family or one of your friends who have clipped nails before. Or you can go to the vet and ask if they can do it for you. But, yes it can be done.
