Bearded dragons make wonderful pets. They have such great character, and I personally spend several hours a week watching my beardie do what it does. As with any other pet it is important that you provide proper care and nutrition for your bearded dragon.
Make sure to start it out right from the beginning; bring your beardie to a vet right after you get him. They can check for any underlying conditions, and get you any necessary medications right away. Vets can also help you understand how to care for your beardie.
When it comes time to feed your bearded dragon, make sure that all food that you give him is the size of the space between its eyes. Anything larger can cause impaction, choking, and even hind-leg paralysis.
This should not be too much of a problem: you should primarily be feeding your beardie small insects. This is especially important for young beardies. Feed him as much as he can consume in a ten minute time frame. When he stops eating, you should stop providing additional food. Young dragons should be fed up to three times per day.
If your beardie is an adult, you should feed them mostly plant foods and supplement the diet with about 30% insects. As far as greens, they like dandelions, collards, grape leaves, mustard greens, turnip greens, watercress, and escarole. Do not forget to give your beardie fresh water every day. They like to move their bowels in their food bowls, so it is essential that you change the water frequently, and disinfect the bowl on a weekly basis.
Every once in awhile you can give your beardie a treat in the form of fruit. They love bananas, pears, plums, oranges, mangos, grapes, and other fruits. Keep in mind that fruits should only be used as a treat.
Humans get exercise by participating in sports like running, team sports, and archery (I write about archery too!). You can not give your beardie a crossbow, so you will have to get them to exercise in a different way. Instead of a crossbow, provide your beardie with a small ping pong ball that they can roll around. If they do not take well to this, there are leashes made for taking beardies for a walk. This is a great way for both you and your beardie to get exercise! You can also set up a bucket of warm water for them to swim in, but make sure to keep your eye on them, and to follow all safety precautions.
