Substrate:
Young Dragons should not be kept on loose substrate. Loose substrates, such as sand, bark chippings etc can easily be ingested – this can be fatal. Even if “petshops do it”, we recommend you do not. We keep our young dragons on plain white kitchen roll. It is inexpensive, and easy to replace. Here is a graphic photo of a dissection of a Dragon kept on crushed walnut. It's intestines are completely blocked by it. Here is an X-ray of a Dragon kept on Calci-sand. Wood chippings and Calci-sand are the two worst substrates for a Bearded Dragon. It may be wise to reconsider purchasing a Dragon which has been raised on either, to avoid complications later in life.
Adult Dragons have a much lower risk of impaction if kept on a fine, loose substrate such as sand. Bark chippings should never be used for Bearded Dragons. There is still a risk of ingestion and impaction with any loose substrate. If you are not aiming for a Naturalistic Setup, it is recommended that you keep adult Dragons on kitchen roll, rough tiles, reptile carpet, or newspaper (check ink is non-toxic first though). If using sand, check there is not a silica warning on the packaging, and sift to remove any pebbles etc.
