Im afraid I have no real experiance with Uro's other than holding them at the reptile store, but I would like to offer my experience of beardies.
Im very lucky as to have brought dragons home at all stages; baby, juvie and adult.
(Its noteworthy however that all my dragons are rescued, and all have some form of disability)
For me bearded dragons are perfect pets because they each have such strong personalities and are very receptive.
Now everyone says "ohhhh they have SUCH different personalities." because they think their pets are the best in the world. But Id like to tell you a bit about the difference between my dragons, hopefully to show dragons individualty.
Prepare for photo spamming! (to help illustrate my point I hope)
Dex.
Dex was rescued as an adult who had been kept in terrible conditions with other species of lizard.
She was missing half an arm and some of her tail.
She was absolutely terrified of me when I brought her home. She bit me, scratched me and hissed at me as much as she could.
With some determination and taming techniques a couple of months later and Dex became the most loving and affectionate pet I have ever had the pleasure of owning.
She would refuse to eat vegitables unless i hand fed them.
She would scratch at the glass constantly in the morning until I would let her climb onto my
bath robe where she would snuggle into and fall asleep whilst I had breakfast.
Ruben.
I brought Ruben home as a 4 month old dragon. He was attacked by his cage mates and was left with two missing legs, and therefore has to have a specially adapted viv.
Ruben was always very independant, he tollerated me rather than loved me, and would always shuffle away given the choice.
However over the last 6 months as he has grown he has begun to enjoy our company. When my partner comes home he will shuffle up to the glass because he knows my partner will give him a little treat. He also now adores to be wrapped up tightly in a blanket and falls asleep on my chest at night. He does however enjoy shuffling around our living room floor alone the most.
Ruben is such a goof (he doesnt believe me when i tell him he is disabled) and cracks me up on an hourly basis.
He is also quite stubborn and will blacken his beard for attention (it turns back yellow after a minute of cuddling) and refuse to eat all day if he doesnt get the type of worm or salad that he wants.
Miso.
My first baby, and only missing some tail, is a huge bundle of energy. She spends all her time climbing, jumping and being generally charming.
She is incredibly confident and knows no fear. She will take a running jump in an attempt to get onto my windowsill from my desk daily, with very bad results.
She shows every promise of being a cuddlebug as she is at her brightest colouring when she is on my lap.
I must warn you though. Once you start you cant stop!
