Can bearded dragons control their growth?

Well, in one way, NO. A bearded dragon cannot control it's own growth rate. However, the cool thing is, YOU can. A bearded dragon will grow in size according to the size of the cage it's in. In simple terms, The bigger the cage, the bigger the lizard will get. however, you must give it at least a ten-gallon tank to live in from the time of it's birth, for most bearded dragons grow to be at least a foot long.
