While it's generally not ideal for your bearded dragon to consume candy or sugary foods, a small, accidental lick is unlikely to cause serious harm. Bearded dragons have different dietary needs, and their primary diet should consist of insects, leafy greens, and vegetables. Sugary treats, like Airheads, can result in digestive issues or other health problems if ingested regularly.
If your bearded dragon seems to be acting normally and shows no signs of distress, there's probably no need for concern. However, it's a good idea to monitor them for any unusual behaviors or symptoms. In the future, try to keep candies and other human foods out of reach to prevent accidental ingestion. If you have ongoing concerns or notice any changes in your pet's behavior, consulting a veterinarian who specializes in reptiles is a good idea.
