Why is my bearded dragon suddenly aggressive, puffing up, and running?

The change in environment may have caused her some stress resulting in a bit of flightiness or aggression. Gradually re-acclimate her to you again. Start slow and easy by simply sitting near her enclosure. Progress to placing your hand in the enclosure for ever increasing periods of time, then to enticing her with a treat. Eventually, you should be able to handle her again. Check environmental parameters to ensure adequate heat and lighting. Maintain a clean cage and proper diet. She maybe approaching a shed which could make her grouchy. The period between 6 and 8 months for most dragons can also be a "grouchy" time....think teenager attitude and behavior. Be patient though, it will pass and she should settle down again.

Thanks for reaching out about Puff and including a photo. Even if siblings, sharing an enclosure can be stressful. Males, especially during sexual maturation, exude pheromones that can be stressful to the others, male or female. Often bearded dragons do not co-habitate well together, and should be kept separate. Good luck.

Bearded dragons in the wild mate in the spring. Captive beardies can be bred year round. Check the environmental parameters and look her over for signs of injury or parasitic infection. This may include redness, swelling, discharge or bleeding. If the behavior persists, consider a physical exam with your veterinarian or a vet experienced in treating reptiles to diagnose illness or injury.

Thanks for reaching out about Rex. The key with taming bearded dragons is gentle handling, quiet movements, and winning trust. Try short periods of handling and offering treats by hand to win trust. Good luck.

Regular interaction and handling is necessary to keep him "tame". Begin by sitting next to the cage for ever increasing periods of time. Move slowly and speak softly around Gunner. He may run to the far side of his enclosure or go hide initially but should acclimate to you quickly, especially with regular feedings. Once he's accepted your presence near the cage, place a hand inside the cage. Make no attempt to touch or hold him. Increase the amount of time as he acclimates once again. You can then draw him closer and onto your hand with treats or food.

Thanks for reaching out about Penny and including photos. Head bobbing can be a result of aggressive/territoriality but maybe also a sign of other problems such as pain. Does her abdomen appears distended? Possibly eggs or constipated? Is she eating? Check and correct water quality for temperature, humidity, UVB exposure and diet. A veterinary visit is recommended to assess and provide a diagnostic/treatment plan. Good luck.

With that black beard, he does seem stressed. Check temps in the cage. Low temps can affect activity in reptiles. Survey the area in and around the enclosure for any negative stimuli. This may include loud noises, strong vibrations, cold drafts or high traffic. reduce or eliminate any if found.
